I find it interesting that increasing number of restaurants are providing tables of suggest gratuities. Not surprisingly the minimum is 15%. (There is no entry for 10% or 12%, for instance.) Neither is than entry for 17%, which is the minimum acceptable tip for decent service according to the Shitty Tipper Database.
I am glad to see that the figures are based on the pre-tax bill and not the post-tax bill. I'm particularly annoyed by restaurants that charge a 15% gratuity on top of the tax and then present the amount as for the customer's convenience.
BTW, the buffet at India Palace was a really tasty.
