It’s a tax thing. If tips aren’t part of the food price, they’re not part of revenue and not taxable. If they are, assuming same compensation as tips would generate, taxes would be higher.
I say put that on the food price. It’s a few cents to the dollar difference. Plus, variations in revenue shouldn’t be a thing an employee should worry about. And obviously it would do away with the whole bartering at the checkout.
