I send out over 100s of packages a month and this location has to be one of the most unprofessional locations.
Short and sweet: lack of common sense, everyone at this location hates there job and is miserable, no patience or any organization, no respect ,Lazy workmanship, poor comments when asking for assistance, not a welcoming location seems like everyone at this location hates there life or even to do there job. People at this location work customer service but lack the personality and work ethic to properly address customer concerns and provide reliable service.

Been here twice now & haven't had an issue yet! Same gentleman was behind the counter both times, and he was friendly. Not OVERLY so, but he acted like a real person which I always appreciate! Thank you!

Was pissily informed by the clerk that they stop taking packages at 4:45. How about everything closing at 5 like literally every post office I've ever been to my entire life.
