My work recently got new credit/debit card machines. Why we installed these memorial day weekend I'll never know, because they are completely different than our old machines, and somehow more complicated. They had different codes, buttons were in different places, satan created them, etc.
It was a long, busy, customers streaming in and out, couldn't sit down, kind of day. My constant line was "sorry, new machines installed, haven't gotten very good with them yet :)" The customers were fairly understanding. The machines can be really picky, where they scream at everyone for not inserting the chip at a perfect angle. This happened a lot.
Towards the end of the day, I was exhausted. I'd been on my feet all day, I had to pee, and I was hungry. All I wanted to do was burn the machines, then take a nap. About 5 mins to close, another customer, a middle aged woman, walked in. (isn't that how it always goes?) I began the transaction, put the chip in, and, as per tradition, it yelled at me. I went to say my usual "sorry" line, but like I said, it was a long day. All I got out was "sorry, I'm not a good person."
It took a second for the words to sink in. She smiled uncertainly, I finished the transaction, and she left. I then slunk off to be embarrassed in private.
Sorry, I'm not a good person.
