She learned a lot of very valuable life lessons working as a server.....most important was how to quickly assess and read people by dress, demeanor, and yes, race.....
Generally tipping varies by gender and race......
The best stories were from Valentines Day, she always worked the night before, which in the industry is called Mistress night. Guy's would bring their girlfriend in the night before Valentines Day and then had the temerity to bring their wife back to the same restaurant on Valentines Day.
My daughter always had the Hostess seat the returning ones at her tables....She said the look on the guys face when he recognized her (knowing his secret) was priceless....The silent look, “I will give you a huge tip if you remain quiet” had to be hysterical....Typically, $100 on a $100 meal or greater.....
She cleaned up on Valentines Day......
Sad. Everybody is a loser, except the waitstaff.
