The question is, "do you believe in tipping"? Yes, I do.
I tip servers as they don't get paid at least minimum wage. (At least not in my state).
I have a problem with tipping hair stylists, lawn companies, massage therapists, etc.
They set their own prices for the services offered. I'm unsure to dole out tips unless the person goes above and beyond. I'm not tipping for picking up a pizza at the counter of a pizza place.
It goes on and on.
