worst part is stroppy or uneducated customers expecting you to rectify any problems after you have looked at it either there and then or f.o.c. someone i know did it for a while but just got bored of getting idiots who tried it on all the time. but i like the idea mate .. not nice hearing about companies who rip people off though, one local place used to just format the hard drives as a solution to every problem and charged way over the odds for doing it..
