Went in to buy stamps and you’d think I was stealing them from this guy’s personal collection. Horribly rude and way too reluctant to answer any questions.

The workers at this post office are lazy and incompetent. Every time that I have been there early waiting for the window to open, it has been late and the postal worker looks at you as though he is being bothered. My mail is often mixed up and they do not appear to care. I spoke to the manager, Jen, on numerous occasions, who simply complained about having too much work to do. Avoid this place like the plague!
