im thinking you might be a little too hard on the guy being upset about broken bolts. Im not sure how you've gotten along so well only breaking so few in your career of working on them, but ive broken hundreds at this point I believe.

I say let it go. He did sit on it a long time on two occasions, which is annoying, but at the same time these cars are not cost effective to work on in a shop trying to get stuff done on a schedule, and an old car always has a cascade of other stuff that will break as soon as you touch it. After leaving a shop, I barely break bolts now, as I can leave them to soak forever.

As long as the problem has been properly fixed, then id say call it even and don't use him again. Chances are the sway bar link was broken when they did the control arm, and they hoped you wouldn't notice because by then they were sick and tired of struggling with the control arm, cursing you the knowledgeable customer, and your old car.
