Normally I’m a big fan of the service charge on a party. This ensures that I get paid for my time and I apply it blindly, regardless of color, age or sex.
I’ve known people that apply “the grat” on only tables that are women, or only tables that are black.
I also know servers who never use it, preferring that their good service earn them a tip, perhaps a better one than the service charge would leave them.
Myself, I believe that I have forged a bit of a work ethic and thus take the safe money, however I do make sure I earn it and don’t rest on my laurels.
Usually its just business for me, but every now and then I do take a little bit of joy in applying “the grat.”
This is because I can read people very well, its part of my job, and I can also read when a table is going to leave a shitty tip.
So I hit the 20% button and out goes the bill and the magic of technology turns a shitty tipper into a good tipper.
I feel happy.
They feel confounded, after all 10% on a party of twelve is more than fair, at least in their minds.
