I have yet to experience an Acura dealership for service. Previous experience with dealers it seems limits how close you can get to the actual mechanic that works on your car.
Don't they usually use the lesser experienced or lesser trained to do routine maintenance like oil changes, and the 'techs' for more involved warranty work?
I suppose if I had a working dialogue with a particular mech or tech, and I found he did a good job on my last visit, I might be tempted to tip him 'to keep up the good work'.
I don't know. It's ok, I just never thought about it really. I've had issues in the past usually with service mgrs. and charges, not because of poor work being performed.
Only one issue with a Firestone station mechanic who replaced power steering hoses under an extended warranty. A great lesson to avoid after-market warranties. The actual job was ok, but he left enough spilt fluid all over the back of the engine and transaxle to start a fire. It didn't, but I almost did when I went back the next day. I got my deductible refunded and lots of apologies but made sure everyone in shouting distance was warned about this service center. Still makes my blood boil when I think about it.....I doubt tipping that idiot would have done any good.
