I am not a tipper. I have given tips as much $200.oo.Blacks are big spenders but bad tippers
A study of inner city black spending habits that finds poor blacks like spend a lot on ostentatious purchases:
"African-American inner-city shoppers are 35 percent more likely than the population as a whole to buy women's dress shoes. They're also 54 percent more likely to purchase teen boys' clothing, and 64 percent more likely than average to buy fine jewelry...While American households in general spend an average of $1,069 annually on apparel, inner-city African Americans spend $1,502."
According to waiters in the restaurant business, white customers tip about 1/3 more than black customers. Blacks tip taxi cab drivers only about half as much as whites. According to data collected from research by universities, African-American passengers tipped approximately one-half the amount of white passengers (African-American passengers are 3.7 times more likely than white passengers to leave no tip). While African-American passengers generally tipped less, they also tipped black drivers approximately one-third less than they tipped white drivers.
If you ask 100 black waiters or 100 black taxi drivers if they prefer black or non-black patrons they're likely to mostly prefer non-blacks. Why? Those asked say that blacks tend not to tip much, if at all.
Sometimes it depends on the patrons financial standing at the time. It is not exclusively a black thing but a "peoples" thing.
