Nope. I avoid dentists (will go when needed but they're my one phobia) and tip a masseuse as per local custom.

The point I was making is that, under normal circumstances, I don't feel guilty about a person's CHOICE of employment. They made their bed, they lie in it.

I know many people in dead end jobs use them as a means of survival while they get the education, etc to get better ones and I totally understand that. I did the same. I flipped burgers, worked as a security guard, etc and do you know how many people felt guilty over my choice of jobs? To my knowledge, none. Do you know how many people tipped me? None. No sour grapes from me, it was a means to an end.

However, those who take on dead end jobs and look at them as a career get no sympathy from me. You made the choice, not me. I will, and do, tip as per local custom and based on service level but I will not be bullied or guilted into tiping. Don't want a tip from me? That's the best way to achieve your desired result.
