OK, here is a shop story from today, not as good as Tommy's but here goes.
Two guys
come in with a belt squealing away like crazy, says I think it needs to be tightened. I look at it and say, well dayyyamm you need a new belt its shredded. He says well another guy said it was fine, I said, no its not, he says, well 3 other guys said it's fine, I said a little more sternly, WELL I'M telling ya now, YOU NEED A NEW BELT, its chewed up, finally the other guy, says no matter, just replace it whatever it costs, well dayamm that's what I like to hear, I took it off, looked as it a rat chewed it all to hell, so I saved it and hung it from his steering wheel, so he could see it.
