I went, sent out about 4 packages (I was selling some things, BPAL perfume and hats I knit) and one of them was returned to my house, with the 'Postage Due' label OVER the sending address, so my mother had to pry it off to even tell me whose package it was. I sent them with my home address as the returning one because the semester is over this week... and I'd wanted to get everything shipped out this week because I live quite a ways from the post office. Instead of it being easy, I have to wait until the weekend to get the package at home, and then Monday to send it out again, meaning that my friend had to wait a week for what she bought from me.
Just, rrgh. I guess it's bad service on the part of the student center staffgirl, who was chatting with friends while she was totalling my postage and putting stickers on everything.
