I'm the opposite. I want a known fee or fare. I don't want to have to think if I need to tip or not tip. Is the tip expected or is it optional gratitude for exceptional service?
No, just tell me the amount. Most of the world works this way. Even in places where bribes are routine, there isn't as much tipping.
Restaurants are moving away, slowly, from the tipping model, mostly due to increases in base wages, making it unpalatable for all but the rich, to pay a premium price and a tip on top of that.
Pay your employees/contractors a fair wage and take responsibility for it, don't shift wage responsibility to the "fare" (paying passenger).
