Right lets break this down :
First you say that you can't train your staff, then how do you expect to get your customers the right product. It's not at the right price, it's at your prices which most of the time are a rip off, yes even rip off compared to other retailers.
The tech guys are a joke, they look down on pretty much everyone the other side of that crappy desk, you freely admit that they aren't trained to standard and pretty much you charge highway robbery for a reinstall of windows. Your 75% fix claim is impressive, but I would like to see what percent your staff are telling people to re-build thier PCs to get a fix.
I've seen your stores recently, the 'tech guy' was talking to a freind of mine who had brought one of your adsl routers, he had asked them if it was wireless before buying it but it needed a adaptor to do that. He was taking it back with me there and god damn if your 'techguy' insisted for a good 5 minutes even after being pointed at the box that it wasn't wireless.
Thanks for making me laugh before I go off to sleep.
