Hahah oh man I have one. I remember one time I went with my dad to my local PepBoys to get some spark plugs and other maintenance goodies for my '98 Civic (yeah yeah, it was my hand-me-down first car) and we ask the jackass behind the counter for spark plugs for a 1998 Honda Civic LX. Now this guy literally looked like some bum off the street dressed in PepBoys attire, about 60+ years old with his long grey mullet and beard. After about 10-15 minutes of "looking" on his computer and on the shelves in the back he returns to say that they don't have them. After this my dad gets annoyed and goes to ask another employee, which turns out to be some manager. He finds the spark plugs we needed in about 30 seconds and brings them up to the counter. Satisfied, he thanks the manager guy and then tells him (in a loud voice so the idiot nearby could hear) "it took that fucking retard 15 minutes and he didn't find shit!". The guy kinda just smiles and I walk away, trying not to bust out laughing. We get the rest of our stuff and leave.
The customer service in that store is pretty shitty. Every time my best friend and I go there for whatever reason, it's like they don't even acknowledge our presence. One time we went to dump like 4-5 quarts after an oil change there and we stood at the service counter for 15 minutes before anyone asked us if we needed help. It's still fun to go now and then though, especially if we need to get a "discount" of a certain variety

We always joke that we could probably roll a set of tires out of there without a problem.
The local Advance isn't as bad, although I still have a story I'll save for later on if this thread continues for ZilviADD's sake.
