Of course, there are also cost traps that you can fall into.
Here are some tips to help you avoid spending more money than necessary:
Eating and drinking in bars:
There is a difference in cost if you eat a coffee or sandwich at a table or at the counter. You can recognise this by whether the tables are served by a waiter or not.
This is where the topic of “Coperto” comes into play, i.e. the amount of usually 2 euros per person when you sit down at a table and are served.
So if you just want to have a crossiant and a coffee in the morning and simply eat it standing up at the counter, you save yourself the 2 euros you would otherwise have to pay at the table.
But if there is no waiter in sight, you can sit down at the table and have breakfast as normal.
