I worked two days a week washing dishes and working the fryer in a sit-down Pizza Hut for six months around 2015, and going to school the other five days. Two nice early to mid-20s waitress of the Caucasian persuasion regularly lamented the times that families of 5+ Indians or Basketball Americans would sit down to eat. Not only would they be demanding and complaining throughout their hour-long stay, but they routinely tipped only what would take the bill up to a flat dollar amount, even if it was just 50 cents or less. This was in a predominately white area, too. I think the Indians came from the McMansions build nearby, Idk where the blacks could have come from.

Those girls would get MAD.

Yes. Worked as a bus boy for a fried food restaurant near a large black population. The black waitresses didn't want to serve the black customers and were more vocal about it. It got to the point where the hostess had to rotate seating blacks evenly between waitresses.
