Needed to take a minute and give a 5-star rating after seeing the negative ratings posted here…read more During our visit, the people working at this location weren't only knowledgeable and efficient, they also took the time to explain the mural on the wall to my 5-year old twins, taught them about mail/stamps/processes, and did all of the above with a smile. I never imagined I would be writing a review about the USPS but the people there went above and beyond and were very helpful! Keep up the great work!!!!

I have had a issue with a international package they tracked and helped me follow up on the status of item. They always seem to have a few sheets of the current stamps out.

Shockingly rude "service" on Saturday, May 30, 2020 at around 11 am by an individual named…read more"Crystal" (no last name provided because "I don't have to"). I was dropping off two large, very heavy postage pre-paid packages. I asked the gentlemen behind the counter if I could leave the package without having to wait on line (absolutely no social distancing was being observed). He said yes and told me where to move the packages. I then asked for a receipt when "Crystal" intervened, rudely, demanding that I wait on line. She then further demanded that I move the packages to a different location. I mentioned I was told to put them there and that they were heavy. She responded "well, you brought them in, and you're going to put them on the scale." I objected to being told to move the packages twice and then was told by "Crystal" that "I am in charge and you will not be served in my post office." Though I had done nothing wrong I offered an apology just to get the packages in the mail. To no avail; I was told to leave the post office. I nevertheless waited on line, thinking, mistakenly, that this would blow over. When my turn came up, "Crystal" instructed the employee at the counter not to serve me. I was forced to go the East Hampton post office, lugging the packages again, in mask and gloves. When I mentioned what had happened, the employees in the EH post office were shocked. I hope the postmaster of the Wainscott post office reads this. He should know how the staff that is in charge of the post office treat the public.
