"Do you have a vacant table?"

Translation: У вас є вільний столик?

[SmithUA01]

what's wrong with "стіл"? is there a distinction between "a table as an item of furniture" and "a table as a thing you might reserve in a restaurant"?

[Vinnfred]

That's just a convention I guess, that we call restaurant tables "столик" instead of стіл

[SmithUA01]

confusing! but thanks for explaining. there's probably something similar in english somewhere

у тебе є вільний столик?

No matter how you look at it, you are unlikely to ask your pal to give you a vacant table or two.

At a cafe or a restaurant you'd want to use ви—which is not as much a politeness device as a generalizing "you" (a waiter does not have any tables—it is the whole restaurant they work at that does)

Is there a way to have Duolingo reply to such answers "Your answer is technically correct, but in most situations to which the original sentence refers, your translation would be considered rude/too polite/archaic/really weird"?

[Vinnfred]

That's a great idea :D
