Re: Has a customer ever apologised to you?
Better than that. I had a regular help requester who was a nice bloke, intelligent* (he was a medic) who couldn't stop himself breaking things (as I said, he was a medic). One day, he had a group policy problem so I emailed him instructions on how to generate resultant set of policy to mail back to me. All he had to do was copy a command line instruction. It didn't work of course. Who'd have thought that spaces matter...
I didn't hear from him for a while and when I next did so, I asked what he had been up to. He confessed: "My PC works much better when I don't fiddle with it."
* He persuaded a research body to fund three months in Hawaii to determine how swimming with dolphins affected mental depression. That's smart.
