Ok... which one of you did this!!!

Once went autobone to buy 1 rod bearing for a 2.5 as somehow I had lost one...i bought some other things and always kind of added up the total in my head (been over charged on several occasions). Got all rung and noticed the total didn't seem right. I asked about and they charged me for 2 bearings because the guy ringing me said there are 2 bearings in the box...i opened the box said "NO DIPSHIT...THIS IS ONE BEARING...TWO HALVES BUT ONE BEARING" he began to argue that it was two bearings!!! He finally told me it was the computers fault even though I saw him scan once then type in two....I hate these chain parts stores. The sad part he is the guy that everybody says he knows what he's talking about...
