I had the most horrible experience at the Bensalem post office on this passed Tuesday, August 30th. My fiancé and I came here to mail our wedding invitations. They were already stamped and packed in a USPS bin, just needed to be hand cancelled. When we arrived, there was no line and the woman at the counter continuously rolled her eyes and basically refused to cancel them. We told her we would cancel them ourselves, but she told us she would do it "in between her customers". We had our suspicions so we informed her that we would wait and watch her until they were all stamped. I guess she wasn't expecting that, because we waited for an hour and they still weren't completed. At 5'oclock they kicked everyone out and locked the doors, but we were still inside (i guess unnoticed). At that point, an older man with a mustache and glasses began complaining that there was no chance they were cancelling all of these "effing" (and by effing we mean the full expletive) wedding invitations. I stepped forward and questioned him stating that we had waited an hour and were promised they would be done in between customers. He said "it's 5:05, we're closed." I told him it wasn't our problem, and that we offered to do it ourselves but were refused. At this point, he flung our bin full of envelopes across the counter along with the stamp and told us to "knock ourselves out". I told him there was no reason for him to be rude to us, and that we gave them plenty of time for them to be completed, especially since they should have been completed when we were at the counter. We cancelled each one ourselves and placed them back in our bin, which took all of two minutes since it is a simple process. I put the stamp back on the counter and told them to have a good night. Now, a week later, we have been hearing and receiving pictures from our wedding guests of crumpled and torn envelopes. I am sure that even though WE hand cancelled them, the post office workers that gave us such grief ran them through the machines out of spite since we forced them to do their jobs. We will be taking this matter to the post master when they open back up after the holiday weekend, and HIGHLY recommend going ELSEWHERE, especially if you are looking to send high priority mail.
