I delivered pizza through college in the late 1980s. Quoting Audrey Levins:
> People of either sex under the age of 25
Among college students, those at the University of Buffalo tipped quite well, while those at Daemen College, a small Catholic school, always ordered a $6.65 special and left us the 35 cents. Always. I have no idea why SUNY students were generally good tippers, while those attending a private school were terrible.
> Women (of any age) who have never worked in–or known anybody
> who has worked in–the service (tipped) industry
Mixed experience here. Delivering to a workplace, my tips seemed to be lower if it was to a group of women, as compared to a mixed or male-dominated group, Also, it was always women that sent their kids to the door to pay, knowing that the kids had no idea about tipping and would likely stiff the driver.
> African Americans
I was friendly to everybody, regardless of their race or their anticipated tip.
That being said, for several months as an experiment, I kept track of the race of the person I delivered to.
The average tip I got from a white customer was about $1.25.
The average tip I got from a black customer was 8¢ or 9¢. Eight or nine cents. It’s an average, because most of the time, black customers didn’t tip; those that did usually tipped about the same as an average white customer.
Selection bias my ass.
> Senior Citizens
A typical senior tipped a bit less than the norm, but a LOT more of them gave tiny tips; either the 30 cents of change, or went out of their way to tip a quarter. I wonder if they were thinking “Here you go, son! With that generous tip, you and your girl-friend can take a street-car ride down-town to-night to see one of those movie-films, and have enough left over for dinner at a fine restau-rant, and the next day you’ll have enough money left over to buy a pair of sock suspend-ers.”
> [del]Tourists who aren’t American[/del] Canadians
Fixed that for you. I mean hockey and curling playing Canadians, not tying to conceal the fact that you’re saying something racist when blacks are within earshot Canadian.
> Americans from small towns/rural communities
No experience in delivering to them, really.
