Yep.
You have to learn when you're the new kid on the block to stay quiet about your opinions of the guys who are working there when you got there. The guys may have been trying to send you a message they didn't want to work on your car.by taking alot longer than they should have. It would have been better to talk to the technician about your car to see what the issues were instead of behind his back. You have to remember the guys at the shop owe you nothing but will protect the other guy's back who they have been working with. If you were not happy with the progress they were making you could have used an excuse to get your car towed from there.
