    Just walked out of this post office again. They can't handle anything and there is always just one guy there. Go to weslaco, 100 times better service.

    just left this Post Office. only one cashier and the line was out the lobby. people kept leaving due to rgr long wait. he took his sweet time. he kept asking customers with pick up slips what their package looked like. umm...i guess he wanted to narrow it down to envelope, package, or box, but last time i checked not everyone knows how the sender packaged a shipment. long story short.... undermanned and no sense of urgency. it took me 43 mins , arrived at 10 am.
