Had this happen to me yesterday:
Went to mail a package. There were 4 stamps on it that were used before. They were all marked out in black magic marker with one line through them. I did not do this, the PO must have done it before the package was delivered to me a few weeks ago.
Well the postmaster was very rude and asked me why are those stamps marked out. In which I responded to her, I recycle envelopes b/c I dont have a lot of money to go out and buy new ones all the time. I don't understand what the big deal was over these stamps being marked out when the postage I was getting was going over these stamps and was a printed stamp from their machine.
I further asked her if that was an issue and she said no but when on to say you can't recycle stamps. I wanted to say so bad, Duh! I know. But I just paid my postage and left.
I was out of town yesterday and found a PO to mail this package. I have never had this happen to me at my local PO. I felt like, even though I did nothing wrong, she was trying to pin something down on me.
Oh well, won't be going back to her.
