Tipping is a western civilization failure that has reaped massive benefit for employers. I travel to Korea, China and Taiwan every year and tipping is not done there; it is not even the norm. I leave for Taiwan in 2 weeks actually. In fact, if you try to tip the wrong person you will get an earful because, too many there, tipping is your attempt at acknowledging to someone that you are of a class better than them. Absolute truth. I could tell you a story oif my attempts to tip an amazing Desert Chef one time that would make you laugh; it is a story worth repeating...but anyway.
Having said that, I tip...very well sometimes. When I get remarked service for anything that I think is worthy of just a bit more of a thank you, I tip. When someone goes outside of their job description to satisfy me, I tip. It is a form of thank you. It is a bit more than just a hand shake. Heck, even with vehicle or house repairs, if the estimate was good and the work was amazing...I will throw a tip and say "Take someone out to dinner on me'. Am I rich? Not a chance...grew up struggling and everyone I know thinks I am selling drugs now to get this car.
On the other hand, if someone insults me, the choice is always nice to not tip, or tip low. I will even tell you that I tipped a single quarter for dinner service once. My server was bringing our plates, brought our food and then her cell went off just before she placed the food down. She rushed putting it down and then answered her phone...getting distracted with a spousal disagreement right in front of us for several minutes...AT THE KEG YET! I figured the quarter was a hint that she could have used the public phone NOT IN FRONT OF MY TABLE eheheh.
Getting specifically to Ron Fellows, I'de bet a million dollars nobody there expects tips and the service there is as amazing as it probably is for the Corvette Museum deliveries. Might I tip? Could I see myself throwing out a couple of 20s and mentioning to my driver to take his closest to a great night out with my help. Absolutely. It is human nature. It is not an expectation and it is not required. It is no more than that extra handshake and thank you.
After all, the cost of 2 day Z06 training is $3846 and GM is covering $2846...I am already plenty ahead aren't I?
