Do shops still sabotage cars for profit?

I was working at a shop and a lady came in and needed her
brakes adjusted, while I had it on the rack the service manager came out and looked at the work order and left, came back and said put new brakes on it, I said why there is nothing wrong with these, he said just do it, I told him to kiss my a*s and rolled my tool box out the door and quit (had been there about 2 weeks), the lady ask me why I was quitting and I told her, she did not say anything, to make it short she worked for the state and it was a kind of sting, the shop shut down the next day.
