Unlike other stations nearby, all the pumps are functional. I don't know when they service the car wash, but I've never seen it down. The air compressor always works ( remember when air was free?

Horrible, here goes- If I could give NEGATIVE stars I…read moreabsolutely would! I do not recommend going here. I have more than a few words about the way they treated me here and for NO REASON! So, Last Friday, I had a tire blowout incident- by Sunday I needed to replace the wheel/tire. So I found the closest tire shop to this Circle K. As I am having my car serviced, im told that they do not accept debit cards- cash only! So I said, "that's fine- Ill go to the ATM" i walk to Circle K, use the atm, say thanks and leave...head back to tire shop. I get there and realize that I've left my wheel in moms vehicle, and now need to purchase a wheel as well. I say, "ok, ill go back to the atm" so I turn around head back to Circle K. This time I needed an odd amount($30), and ATMs give even bills. So I withdraw $40 and am already stressed at this point, I walk up to the counter and ask politely if they can do change for a 20. The clerk rudely says "no, I won't do that, we dont have change here" so I walk to the drink cooler and grab a redbull. I set it on the counter w/1 hand &a 20bill in the other, ready to just purchase a drink. I figured in my head that if they cant do change, they can SURELY let me have my change after I buy something with MONEY, right? NO, the clerk got nasty and disrespectful with me and actually told me this-"you're gonna have to get closer to 20 than that!" Basically telling me that I couldn't just purchase the redbull, I was expected to spend more of my money at "his" store in order to make the transaction and get my change. He goes on to say this after telling me that no I cannot buy this drink...he says-" well- the cats outta the bag now that you just need change so, im not selling that to ya" so i walked out, no drink, or change, no transaction whatsoever and straight across the way to the liquor store- they helped me right away, I told them briefly what had happened and they were so helpful and kind. I offered to buy something and they said there was no need-and handed me change no problem. Apparently they know of the CircleK clerk, he must have a rep for this kind of social misbehavior- Needless to say that this man needs etiquette lessons and maybe a BUSINESS CLASS so that he can learn that you dont ever treat someone that way in a "professional" setting, a stranger, especially your own repeat customer, and a person that was IN NEED at the time, as well as low on funds, like honestly I couldn't even AFFORD THE REDBULL BUT HE WAS SO RUDE I JUST NEEDED MY OWN MONEY BACK, (BUT LESS OF IT!!!!) Like dude, im trying to give money to your business in exchange for my own $$$ seems like he just lost a lot of customers....some people's children.......
