They close at 5p. I got there at 4:30 and there was a sign on the door that says “closed for lunch 4-5p”. How is it okay to close an hour early?

Don’t greet customers.. make you take your packages and act like we’re bothering them at work. Disrespectful and argumentative. When you ask for a supervisor you get an even louder and disrespectful person
