I did. Long before the FedEx take over.
I once had a woman bring in her only copy of her master’s thesis (!) on a single floppy (!), and then proceed to lose half of it on a self serve computer. She blamed me and told my boss I was ogling a young woman across the store instead of doing my job.
I had a customer try to order copies of a KKK calling card.
It was the days before home scanners were ubiquitous. We used to get a couple people a month bringing in dirty pictures of themselves for us to scan, put on a floppy, so they could post online (AOL usually). Naked. Peeing. People were shameless!
Police came and dumped all the data from all our self serve computers after a coworker with a mental illness lied during questioning (for an unrelated crime) and claimed to have been running a credit card identity theft operation out of our store.
Almost asked a man to take his bare feet off a computer mouse, before noticing he had no hands, and was operating the computer with his feet/toes!
