Guess we have to "agree to disagree". I tip on the service provided, not what their hourly rate is.........
That gets back to the same interminable arguments...would you tip in Japan, where the locals don't tip and waiters are well paid? If you "tip on the service provided", then you must tip the Tokyo waiter, even though it is a culturally insensitive thing to do. And why don't you tip grocery baggers, fast food workers, department store salespeople? They provide services too.
The fact is, people don't actually tip based on the service provided. They tip out of habit, they tip because 'Mama brought me up right'. And they make up arguments about service provided.
You don't "get it", or I am being obtuse... I guess I need to EDIT my response. Of course I wouldn't tip where it is not socially accepted, (in your example, Japan) and I HATE the tip jars for any RETAIL establishment, or food service where they do nothing for you at all but enter your order into a POS or ECR, and then just hand you the food.
But the
reason I tip is not just one thing. At a bar, (or with an LSA working the cafe car) I wish to be "remembered" and provided with great service, like maybe having my drink/beer ready by the time I get to them. Or stashing the last bottle of red wine for me. Or any number of things. I make it clear to the TA-S that when I board, "I'll take care of you at the end of the trip, as long as you take care of me----" With a smile and a wink. Disarming hopefully...Trust me, I have "stiffed" many a TA-S, who have never bothered to even poke their head into my room and say "Hello".
Ever been in a SSL car, when coming to the end of the line, and they announce "Please return to your seats, and prepare to detrain, the lounge car is now closed........" Guess who gets to "stay" or is not shoe'd out by the LSA? Because he/she made $10-15 bucks from me over the last few days.
I'm certainly not saying one is obligated to tip, no one is. But under the same argument, no one should be made to feel bad FOR tipping also. I too delivered pizza in my day, and also found that the best tippers did indeed seem to be those that (just a hunch here) had also been involved in the service business at one time or another.
Do you tip the Red Cap? Hotel Doorman for getting you a cab? (guess what happens next time, if you didn't...) Bell Boy? Room Service? Do you leave something for the maid? I normally do not, but I also post the DO NOT DISTURB sign on the door for the entire duration of my stay. (I figure if I use the same bath towel at home for a week, why can't I while in a hotel, saves on the environment too, just a wee, wee, wee, little bit...)
So tip or don't tip, I could care less. As for me, I appreciated it when I was in the service industry (on Amtrak and on "land") and I like to reward really great service.
