Setting: at an upscale restaurant taking a customer's order, we now get to the drinks.
Me: And what would you like to drink?
Customer: "7R-Block."
Thoughts ran through my head: What the heck is that? It sounds more like a tax firm than a drink.
Me: Hmm, I've never heard of that one. Is it a mixed drink?
Customer: I know you have it, I order it every time I come here.
Me: Okay, just hold on for a second, I'll be right back.
I went back to the kitchen and asked the other workers if they have heard of a drink that is called 7R Block. Perhaps it is a "secret code" used by the employees that I haven't been taught yet or maybe some kind of slang.
Me (to employees): We've got someone wanting a "7R-Block." Do we have anything by that name here?
The employees haven't heard of it either, and recommended that I give the customer a menu with our complete drink listings and have him point out what he is referring to.
Me: Here is our complete menu. You can point out exactly what you want.
What did the customer point at?
