I love going into PC World and messing them about lol, I asked ages ago how much a 6800 was...and they said they'd have to check the washing machine bit...
Then in Currys, a couple were asking what RMS stood for, guy said "Real Music Sound" ... oh god that was hilarious, my uncle then went over and corrected him - needless to say, the couple didn't buy anything from Curry's that day!
