My aunt used to work customer service at Sam’s. One day, a customer was not pleased with the answers she was giving him, so he asked to see a manager, and “not a black one.”
So she got on the Sam’s PA system and announced, “customer at the service desk would like to speak with a manager…and not a black one.”
You’ve never heard a Sam’s go that quiet! After the initial gasps, you could hear the footsteps of a manager trotting to the CustServ desk.
Dude was clueless that he’d even asked for something controversial.
The preferred nomenclature is "you people."
