After eating at Chuck's Tacos, I had to pay a visit to Circle K as it was part of my early years when I was a young adult. Thirty plus years ago, I was an employee at this Circle K in Upland. Yep, I used to work at a convenience store. They are story only... no gas station. Upon entry, I was amazed on how well kept it is. Bright and clean inside. Shelves were stocked and organized. They now have a beer cave. I said, WOW! After so many years, it looks better than ever. I strolled through all the aisles. It brought back so many great memories! When I worked here, it was a corporate store. Now it is a franchise. I was lucky to meet one of the franchise owners, Kevin. Super friendly and nice guy. I wish him and his brother all the very best in making this the best Circle K in town. Staff was amazing, too! I couldn't resist and had to buy something to support them. I got one of my favorite candy, Reese's Pieces, and $7 worth of scratchers. I still haven't scratched them. I'll save the scratch for Christmas Day. It was great to receive some wonderful nostalgia during my visit. I'll return to visit from time to time when I'm in the Upland area. Happy Circle K! read more

So I made a early AM stop for an energy drink. The store is in a strip center. Entry from foothill is not to difficult. There is ample parking and it is well lighted. Unlike the 7-11 across the street. There were people hanging out at the front of the store. Inside it was well stocked and organized. I found what I wanted and went to the register. The cashier eventually came up and silently rang up my order. The only acknowledgment I existed was the items her scanned otherwise I have had more interactions with a self check out. They charge a $0.40 service fee for using a card. A bit high. This location has a Thrifty ice cream counter. Would I stop at this location again ? Yes if I needed something quick . Would I pass up an other convince store to go to this one ? No. read more

Stopped by here and bought a lotto ticket for $10 for the billion dollar prize. I did not win the lotto, but I did leave with snacks that held me over until after the club. Place is small, but they are fully stocked with drinks and snacks. Cashier was really nice and at the time it was a Friday night and there was some major pressure washing happening in the parking lot. read more

As of 08/12/24 nothing in the store is charged at the prices listed. Signs everywhere of all the deals they have just for the cashier to tell you no they're old and aren't valid anymore. Blatant false advertisement hoping you don't look at the price when you pay read more

The cashier claimed a $20 bill was fake cause a pen turned the bill brown, and so I paid for my purchase and asked her to mark a different one of my bills. A $1 bill, and that also turned brown. Why would I have counterfeit $1 bills? She's just false marking bills and pocketing the cash. read more

Don't buy milk from this circle k. Note said to ask clerk for dairy so we did. The clerk went to the back to get the milk and this is what we got. Milk is still "good" for another week but there's nothing but clumps in it. I'm sure it sat out for a while and spoiled in the California heat. Never had a problem at the circle k south of foothill. read more

Great staff and the store is always clean. They always have great selection of beverages too. Love the Beer Cave

What is Circle K is not convenient? Great selection on fountain drinks for $.88 polar pops, great for road trips. All of the staff is very friendly I never encountered anyone with an attitude. The only thing I dislike about the store is there are a lot of homeless and drug activity. Another thing I dislike is the smell of the store I feel sorry for the employees it smells like sweaty ass/sewage. This is an honest review I hate to post negativity hopefully they can resolve this issue. read more

I knew to always check expiration dates on candy at this store, but I bought some quaker rice cakes and found mold inside and that they were expired. I tried to look past the mold/meldew smell near the soda fountain but this is gross, almost as bad as the time a string of mold came out of the fountain and into my cup. Someone needs to seriously check the health of this store. read more

7/17/23 between 10 PM and 12 AM my friend and I walk into our local circle k it's the nearest and only store near our house we come there almost every day and have never experienced an issue. As we walk into the Circle K to grab our female necessities the woman working the register begins to yell across the store at my friend demanding her to leave that she can no longer be in the store. I walk outside the store with her and ask her to wait outside for me I'll just go in. I walk back In began to wait in line watching the woman check out a customer in front of me something seems off about her I believe she was under the influence of drugs her eyes were very dilated and hands were shaking she was having difficulty counting the money and checking out her customer she almost shorts them $40 they end up having to ask her for it. Finally it's my turn I placed my item on the counter the lady begins screaming and harassing me in front of all her customers saying malicious things about my friend who is waiting outside patiently. The lady grabs my personal feminine product throws it under the counter and demands that I leave and never enter the store again because I didn't agree with the malicious things she was saying about my friend outside. The whole time as I entered the store I was silent minding my business just trying to buy my personal product that I desperately needed but no she denied me of my right to my personal necessity. The women name Christina chose to inflict her personal opinions on the customers causing drama in the store instead of being professional and correctly fulfilling her job. she screamed harassed and caused a scene in front of every customer in the store. I am very disappointed me and my family have been coming To this Circle K since I was a child we come there almost every day and now I can't even get my daily necessities without worrying about being harassed by a woman Who values her personal drama over her own job. read more

Went in and they said they were closed. It's a 24hr store and I'd get it if he were taking his break but he was very rude.
