And sometimes they simply get the best of you. Some of these guys are masters at wasting your time and they can use up a lot of it. They run the same show over and over again and they can use up hundreds of man hours every year while vendors trip over each other to satisfy these jerks.
Had one recently who wanted some sleeves for his engine. I gave him a price of 36 dollars each. Then he wanted to know the size, material composition, press fit requirements and a dozen other things. I answered all of his questions and then he tried to grind me down on my price. Considering that I was going to make 36 bucks on the deal I really didn't have any room. He kept at me and finally I told him that if he continued to grind me and use up all of my time that I would cut him loose. Then he asked for something else which he also grinded me on. Then he called me from Lebanon..........saying that my emails were getting too tense.
So, I ordered the sleeves for him. Considering how much time I had spent on his guy I wanted to recoup something - anything......... Well, I should have cut him loose ' cause I still have the sleeves........
He went from 20 emails a day to zero after I told him I had his part in stock. His way of getting even with me for challenging him I suppose.
