I took my truck in to the shop to get the back breaks fixed. About 10 o'clock the phone rang. The mechanic on the other end asked me what was I going to do with the back breaks. I asked him what he meant. He said that the front breaks were fine but the backs had a blown wheel cylinder. I asked him why he was looking at the front breaks anyway. I told him that he was to get the back breaks fixed and not the front. He said he would stop on the front and looked at the back. After the breaks were fixed I went to Wal-Mart to buy a tire. I told them that I wanted to mount the tire on the rim on the right rear side and then changed to the spare. (The spare tire is is on the right side rear) and I wanted to replace it with the same tire that was in the back of my truck (the same tire that was on the truck). There was NO one in the shop at this time. After about 45 muinets the truck was brought in and they called me to the shop. They told me that I couldn't buy that tire. I went and looked at it. They had the wrong tire broke down and ready to change it out. I said no that is the wrong tire. But since they said I couldn't buy that tire they were not going to sell me one. The only reason they gave is that it is a different size. Since the tire is to be used as a spare I said they were wrong. The argument got totally out of hand so I left to buy a tire in another store. When you ask people to do something for you and pay them to do it, they should listen. I used my spelchecker (My wife).
