- JAJim AllenMar 27, 20224.0I've always been treated well, and have been thrre since 2012. I lost a key, staff's been slow to replace it. That's little enough to complain about

- KSKymberly SparksDec 16, 20161.0If I could give it less stars I would! Gentleman with an accent was mad I came in at 4:48pm because they were closed... No, in 10 minutes I stated (it took him 2 minutes to sell me the stamp I needed)...& He argued with me that they were closing!
- SGSyburiz “Syburiz” G.Jun 8, 20132.0There are two guys at the customer service window. One that has been there for awhile is very professional the other guy with an accent is extremely rude, and seems to not understand what he's doing. I have a P.O. Box there, so when I go to check my mail or have a big package to ship I try to come in on the hours of the older profession USPS employee. Stay away from the guy with the accent and you'll have a better experience at the Knightsen Post Office.
