I have never been a fan of post offices. This one had a long line in the middle of the morning. If they had an electronic mail station it would be much simpler. Instead you have to wait in a long line just to have an extremely rude employee assist you in the mailing process. If you need me to sign the back of my credit card, explain that to me. No need to be a dick about it. No one signs the back of credit cards these days. There are multiple locations in Mesa, go to another one.
