The tipping standard for restaurants is 15 to 20 percent. For gentlemen, the standard is 20 percent. If the service was impeccable, feel free to tip above 20 percent. Many people tip after tax, which is fine if that’s what you prefer. The correct way to calculate your tip is using the pre-tax total.
