When I first joined Novell, many moons ago, many of my colleagues had worked in WordPerfect application support (in fact that's still true). The topic of 'users' came up (how come such an innocuous word can have such negative connotations? Like 'interesting' and 'special', but I digress). They had lots of stories from their years in support. Now, they may have been pulling the leg of the poor naive newbie but I'll share them with you as they still make me chuckle.
There was the one where a user was asked to send in a file to email@example.com - 3 weeks later an envelope turned up with firstname.lastname@example.org written on the front - and a floppy inside.
Then there was the one where the customer sent in a 5 1/4" floppy with a "With Compliments" note stapled to it.
And another customer was asked to send in a copy of their disks, so they sent in paper photocopies.
Then around the time that the GUI version was released there was a comment in passing from a woman that did a lot of sewing. She complained that the 'footpedal' made here feet ache - she was trying to use the mouse with her foot, like a sewing machine.
And then my favourite two. Apparently these took days of troubleshooting. The first one was a guy complaining that every time he pressed the letter A, a Q was printed on the screen. After much to-ing and fro-ing he admitted that he didn't like the position of the A on a QWERTY keyboard so he had prised it off and put it where the Q was.
And the last one was a lady complaining that spaces got randomly inserted into her documents. This ended up with someone going onsite to watch what she was doing. After about 10 minutes of observation the fix was discovered. Let's just say she was a large lady, and moving the keyboard slightly further away from her chest resolved the issue.
