Alguien puede decirme para qué sirven los bonos obtenidos con cada secuencia de preguntas?
Esto dicen en Internet: Check and bill should be interchangeable. The important part is to a have fully qualified sentence, e.g. "Can I have the bill/cheque please" or "May I have the..." or "Could I have the..." In American English, in a restaurant context, "check" is more common than "bill"; if your server is across the room and you want to discreetly signal for the check (without shouting across the restaurant), you can make a ✔ (check mark) gesture in the air with your index finger. I can't guarantee it will be universally understood, but it has very wide acceptance in American restaurants, and even if it's not understood it won't be considered rude.
