It’s the same as the VAT. You can calculate it. But you shouldn’t need to do math before going into a restaurant just because the owners can get away with expecting you to pay more for something advertised as costing less. In most other countries, shops have to include VAT in the price they advertise. If I see a 25€ item, I know I will pay exactly 25€ for it. And if I see a 20€ meal, I know I will pay exactly 20€ for it.
If restaurants expect you to provide at least a 20% tip, they should advertise their menu with that 20% added to it. Else, I’m gonna pay exactly what’s on the sign.
