I know this conversation is dead but I wanted to add my two cents. I worked for Les Schwab Tires in Ellensburg, Washington for long enough to see a set of these come in on a small dump truck. The owner spent some time trying to bully me into working on them. Tried to make it my fault that he owned them. "All he wanted was a flat repair." I told him all I wanted to do is go home to my wife that night. It didn't seem to bother him that my death could be an option. He wasn't the only one to ask me to do unethical things while I worked there but it does stick in my mind as a highlight of my career to see them and to tell them, "nope, please leave!"
