I knew someone who was a waiter at one time working full time at a restaurant. When he began work, he found some customers would not leave tips. So he would cordially ask the customers if anything was wrong with their service. And inform them that for people in his line of work where they serve their customers, their earnings are mostly based on tips. Minimum wage is different for tip receiving employees, but if the tips do not add up to normal minimum wage, then the employer is required to supplement their paychecks until they hit minimum wage. So if you like the service that the waiter brought you, you got to tip. The money goes to them only. If you get a haircut, then you got to tip if the barber/stylist went a couple of steps further and made sure you got the haircut you like. You got to show your appreciation for workers who went above and beyond their requirements to serve you better.
