Parts Store Rant, the other side of the story

i know all the guys a t my local AZ and 4 out of 5 know their stuff one even has a 440 duster I have bought parts from him but I also used to work there so when I go in I just grab an empty computer and look up my own parts and let them get the parts from the back I was told that custmers are allowed to look up their own parts but no one tells them that so next time your in O-zone get on a computer and see what they say
