IMHO Midas has that name for a reason. Every tech there is required to try to turn every single job, even on e as simple as new windshield-wiper blades, into gold. By any means necessary.
I don’t know if they still do, but they used to weld up new exhaust systems using their “lifetime guarantee” muffler. The muffler would quickly rot, and the patron would return to get the free replacement muffler. Of course the patron had to pay for all the new piping, the new welding, and all the miscellaneous parts all over again… at inflated prices… but the cheapie muffler was free!
Midas had another trick. They recommend major work on every car that came in, whether it needed work or not. If the patron declined, they’d stamp in big red letters “UNSAFE TO DRIVE” on the customer copy of the shop order to scare him/her. Every shop order. Every time.
They were caught pulling these tricks by an AG investigation in one state, but I doubt if it changed anything.
