Sounds about right.
At least you didn't have to tell them whether to use left click or right click... I've had that several times. When I was in college and working at the support desk there (we assisted both students and staff at where I was positioned), we always had 1 staff member notorious for that... He also tried to type an email into Google (the search engine...not GMail). Everybody there had his number memorized, so when we saw it on the caller ID we all groaned and knew a 5 minute call was going to be 30+ minutes.
Haha yep plenty of people like that.
I've had a 70 minute call before for a tablet issue, which was quite painful. It was a combination of quite a tricky issue to solve, and an incompetent user. The two combined... *shivers*
