Well, she's kinda right. I waited tables for years in my youth, and did very well on tips. Bought my first home with tips.
In recent years I overtip for good service. By a lot! But I have also not tipped a penny to 'don't give a fuck' attitudes, bad service, and uncouth baboons who have no business out in public. It's always blacks.
They should be proud of their 'slavery'. It's the last time they contributed to America.
