I have a believe that for the whatever price it charged, it should includes food and service already. For example, most fast food restaurants offer simple food with minimal service, that's why their prices are relatively cheap; but for a fine dining restaurant at a 5 star hotel would offer much quality food and service, and thus their prices are much more expensive. Therefore, regarding for the tips/gratuity, since the price on the menu already includes food and service charge, only if the server provides extraordinarily good service, I really don't think why they should get more tips than usual. And yea, I only calculate tips before tax.
