Seeing a thread on Slashdot about anecdotes from technical support reminds me that I haven’t posted mine here. So, time to start. I’ll be limiting myself to stories of things that either happened to me personally, or happened to a colleague I was working with; no “friend of a friend” stuff.
There are stories of more dubious provenance at rinkworks.com. I love their quote from Charles Babbage, which has to be the earliest example of a clueless user story.
