Yep.. I've never been sorry to get away from tech support role.
20-odd years ago now, 3 hour round trip to plug some effing speakers into the correct socket on the back of a PC. I'd not have minded quite so much if the plugs, and sockets, weren't colour coded, so it should have been bloody obvious.

I think this was at the third company this bloke had set up.. The previous ones had both gone bust. I assume his business skills were on a par with his colour-matching skill
