Do you have a link or is that something you heard in your inner circles? I've heard from waiters and waitresses that Christians, on Sunday, after church are the worst tippers....and that's a shame, and that includes all races. That's why I like to tip big....
There are definitely certain demographics, including racially based ones, that are pretty bad tippers. I think, however, that what you are referencing needs to be understood as a
crowd as opposed to a single party. The Sunday after-church crowd is certainly the worst group in some ways, because they tend to compose the entire customer base when you see them. You don't just get one table of the church crowd, while the rest of your tables are "regular" people. The entire restaurant fills up with them, your section is full of them, and the constitute the vast majority of the people you will wait on during your shift that day. It is definitely the worst
crowd because you get consistently poor tips from just about every one of your customers. To make it worse, they tend to be very demanding. So you've got a full section of exceptionally demanding guests, all shift, all leaving lousy tips. Church goers generally tip in the 7-10 percent range.
Statistically, black people do tend to tip badly. I'd say that ~75% of black people a predisposed to tip no more than 10% regardless of the quality of your service, and 50% will tip 0-5 percent, with many stiffing you. So, when you compare 100 black people to 100 church goers, the black demographic is the "worst" in that you will get the least money overall. But the chances that you will ever have a
crowd like this is extremely small. So even if this one table tips you poorly, you have the rest of your section, and the rest of our shift, to help balance it out. Whereas, the church crowd almost always comes as a crowd. You end up with few to no other guests to compensate.
Now, the interesting thing here is that when you compare white church goers to black church goers, there's a reverse trend for both groups. What I mean is that when you get a table, there's a valuation that you begin making as to how much money you will make from that table. It's a process, but it begins instantly when you see that you have a new party. This is just part of how it goes, as pertains to the tipping behavior of certain demographics:
-Table of white people: Most likely 18-20% tip. If you screw up, 50/50 chance your tip will go down.
-Table of black people: Most likely 5% tip. If you screw up, 90% chance your [meager] tip will go down.
**When you greet your table**
-White people are church goers: Tip expectancy goes
down to 10%. If you screw up, chance your tip will suffer = slightly increased.
-Black people are church goers: Tip expectancy goes
up to 10%. If you screw up, chance your tip will suffer = slightly decreased.
