Why Tipping Matters: There are no written rules for giving gratuities, but
it's expected at places where service workers are paid only minimum wage or commissions. You
are not legally required to leave a tip, however, you’re being very unfair to your server if
you choose to be a cheapskate. Many servers completely rely on tips to survive. Keep that in
mind before you bail on a good waitress/waiter.
U.S. Standard: In
2019, the minimum amount to tip is widely understood to be between 15 and 20 percent.
