- In the passage, you enter a restaurant and first, you take a seat. Then you receive a glass of water, setting the context of dining.

- Next, you take your time to decide what to order. This implies a typical dining scenario.

- When a waiter appears, you ask about the menu. A waiter in a restaurant setting is typically the one who takes orders and serves food.

- The mention of asking, “What do you have?” is directed at the person reciting the menu, which is often the waiter's role.
