Re: Not me...
The same operator once caught me away from my terminal. Policy was to log off when you left your desk, I was just running around the corner and in the middle of a big edit, so I left the terminal logged on.
When I came back, he had made some white space in the middle of the file and prominent in the middle of the screen was the sentence "write out 1,000 times, I will log off my terminal, when I leave my desk!"
So, I opened a new file, wrote the sentence and copy and pasted it 1,000 times into the file (macro). I then exited the file and started the VAX Phone utility (a forerunner for ICQ and everything that came after it). The operator answered and I piped the file to his terminal! :-D
I once met a senior manager who was on the receiving end of something similar. A secretary at one of his customers was working on an email to send to the SM, she left her desk to carry out some task quickly, came back and sent the email... Only, while she was away, some joker had written some inappropriate text in the middle of the email, along the lines of a nice rear and wanting some hands on experience with it... The poor woman was mortified, when she found out, but, luckily the senior manager at the supplier thought it was absolutely hilarious and was laughing and telling everyone about the email he had received, so there was no damage done to the relationship between the two companies. I don't know hwat happened to the idiot that typed the message...
But another time, I was working late, along with a couple of other people, when the site manager came in and ordered everybody to leave. I told him I had a deadline, he said, no problem, he'd talk to the customer, leave NOW!
I found out later that a colleague had gone up to the his PA, opened his trousers and plonked the contents on her desk and asked her, what she could do with that... She said she needed a second opnion and called her manager... That was why we were asked to leave, he was marched in, once we had left, to clear out his desk, never to be seen again. I have no idea how he explained his sudden lack of a job and, probably, impending prosecution, to his fiancé once he got home. Again, not me, but that was a very expensive mistake for the colleague, and I would assume devastating the fiancé and traumatic for the PA.
