Dude!!! You screwed up and you are looking for someone to blame other than yourself.
I have never had a bad experience there, in fact, my experiences have all been very good. Everything that some of the other people have mentioned, like removing of the CF card, battery, anything that is not causing problems is removed and returned to the customer, is SOP(standard operating procedure) for cameras being sent in.
I have even met with one of the senior techs to explain particular issues I had, they all were addressed resonably though not totally solved(it'll take too much time to get into it). I have even asked for a ridiculous turn around on the shutter replacement on my camera, it was done as requested or rather insisted, though they told me normal turn around would be like 5 working days, I got it the next day. Had a shoot no back-up so they did it without any attitude or rudeness.
Maybe your case is just an isolated incident and for those who got attitude from the staff maybe you were just being an obnoxious jerk and they treated you as such. If you are nice to them and they turn around and are rude to YOU then that is another thing. But if you were a jerk from the get go, I would say you deserved what you got.
