double grat 

When a server, who doesn't inform a guest that the gratuity has already been added to the bill...and the guest leaves a gratuity on top of the total of the bill. Usually accidental when guest pays with cash, but can happen purposely with an additional gratuity line on a credit card receipt.

"I just got a double grat on table 23!!"

double grat scam 

A restaurant server not informing their guest that a gratuity has already been posted to their check (as is policy in many establishments on tables of 6 or 8 or more guests), thereby the guest tips again not realizing it has been included, resulting in the waiter receiving, basically, a double gratuity.

Yeah, but that made his night. Ahhh, the double grat scam...

Doublerationality (Social Control Theory)

A condition where what counts as “rational” depends entirely on who is speaking. The powerful’s self‑interest is called rational; the powerless’s self‑defense is called irrational. Doublerationality is the gatekeeping mechanism that defines rationality itself as the property of dominant groups, ensuring that dissent always appears unreasonable.

Doublerationality (Social Control Theory) Example: “The CEO’s bonus was ‘rational compensation’; the worker’s demand for a raise was ‘emotional entitlement.’ Doublerationality: rationality as a privilege, not a practice.”
