Car repairs can cost quite a pretty penny. Anyone unfortunate enough to have made a trip or two to a mechanic knows the fix will never be cheap. It's probably our own fault for ignoring that tiny little light on the dash and thinking that thumping sound was a problem for another day, but details aren't important. Luckily for this guy, his wife's sister's boyfriend (we promise it's less complicated than it sounds) is a mechanic. There's just one little problem: they hate each other.
So the Original Poster (OP) in this story is dating the mechanic. After he fixed her BIL's car, he asked for a really reasonable price in return. If the BIL had gone to a shop, the cost would've been nothing short of $900. Instead, he only charged him $150. A fair discount, the mechanic boyfriend thought. Well, the entitled BIL nor his wife (the OP's sister) thought being charged was reasonable. Keep reading to see how things escalated from there.
