Good news: they had 3 people working the counter today, so the line moved pretty quickly.
Bad news: one of said employees has a major "Alpha Male" thing going on and was condescending to customers, loud and annoying. Avoid the middle-aged guy with the gray curly hair and glasses. In addition to being rude to customers, he roughly tossed a woman's Priority Mail package WITH FRUIT IN IT into the mailing bin when she wasn't looking.
