Translation:Do we give a tip?
The answer sounds completely unnatural to me. I don't "give" a tip unless I'm telling someone a tip, but rather I "leave a tip," or I "tip the server." In the US, the action of tipping is socially/ethically mandatory as payment for service, so "give" feels off. In China, I never really observed tipping was much of a thing outside of really touristy areas, and mostly expected of tourists.
