Here is a piece of dialogue between waiter and customer in the restaurant.
Waiter: ‘Hello, sir! Please come this way, your table has been reserved!’
Customer: ‘Thank you! Can I have the menu, please?’.
Waiter: ‘Certainly, would you like to have regular water or mineral water?’.
Customer: ‘Get me regular water, please’
Waiter: ‘Sure Sir!’.
Waiter: ‘Here is your water and the menu. Do let me know what you wish to order!’.
