Another solution is “fire the bad customers”. You can’t do that in a literal restaurant while a party is eating, but in most businesses, there’s a slice of your customer base that isn’t profitable to serve, never will be, and when you find them rather than staffing up to serve them, consider sending them away.
If you can gift them to a competitor, you can double the win.

You can absolutely do that in a literal restaurant while a party is eating, though that's normally for customers who harass and disrupt other patrons, not karens.
In about 6 years of waiting tables I cut off exactly one party from alcohol… they threatened to shoot me in the parking lot later. Probably was the right decision, but not an easy one to make.
