Same meaning in my experience. The patron is kicked out. 86'd is the past tense. 'they have been 86’d'

You no longer have any of that product, ingredient, or in this case customer.

No, "86 the chef special" means 'kitchen is out of chef special.

Yes, your task is to remove it from the menu.

But you aren't 86ing it.

You're marking it as 86'd because the quantity is below minimum threshold (usually zero).

str 86;

str itmTo86;

86='get rid of';

info(strFmt('%1 %2',86,itmTo86));

(This won't actually work, since you can't assign ints as variables, but whatever. It was fun)

And that’s the joke behind Agent 86’s number on Get Smart. He’s a bad agent, and someone should have gotten rid of him.
