Tipping is like blockchain and Brexit: important, but super confusing. When and how much to tip can depend on any number of factors, including the specific situation, service, or even the location. Tipping used to be about showing appreciation for good service, but as minimum wage has plateaued (federal minimum wage is $7.25), workers have come to depend on it. What’s more, only seven states require tipped workers to be paid minimum wage before tips; in other states, their wages start at $2.13 an hour. So how do you make sure people are properly compensated, especially when most service-industry workers depend on gratuity? Consider this your go-to tipping handbook for knowing exactly when, whom, and how much to tip at any given time. (You’re on your own with blockchain, though.)
