A sears auto center cross threaded 15 out of 20 lugs on my mothers car when they put tires on it. Blew me off acted like i was trying to rip them off. Pretty much told me and her to eat s##t and die. I had to change all the lugs on her 84 Buick. Strangely enough i heard someone went crazy with a bottle of super glue one night at the auto center. Suprising number of locks on doors there. Just what i heard.
