Discount Tire just lost my business

I lost it and cussed them out over the phone when I had dropped my truck off for a rotation. They called me to say they couldnt do it because I needed my best tires on the rear. I told him I paid my money for my tires and he better f***ing do it because I paid for lifetime rotation. He said he was sorry but it was store policy. Afterr a couple minutes of verbal explatives that would make a sailor blush I calmed down enough to tell him i,d be up there in an hour to pick the sob up. When I got there he had went ahead and put the rear tires up front. On the back was a brand new pair of Goodyear 275 50 20s. No charge. Well he shut my foul mouth up good.There was no charge. So I bought certs on them apologized and slithered out of there. They have a customer for life. I guess for every ying theres a yang.I am now one of their politest customers.
