You will go to a restaurant and they will say they have ran out of menus. You will asked for a normal pasta that maybe you have had elsewhere and a drink. At the end of your meal when you get the bill it will be double what you were expecting or should be paying.
Tip – Ask the price for anything you order before you order it. If they still try to charge you more ask for a ricevuta fiscal – an official tax receipt. Know that some bills may include a tip or if you received bread on the table they can charge and recently European cities are charging more to eat inside the restaurant.
