In Italy tipping is very simple. Normally the tip is included in the bill, called 'coperto' on the bill. If not included, no 'coperto' on the bill, one gives a 10% tip, same as in Germany. If 'coperto' included one can leave 1-2 Euros on the table, showing appreciation for an extremely good service. In bars no tips are expected. Taxi driver bills get rounded up.But when I’m in Rome, I’ll tip as Romans do. Especially when I was satisfied and wish to come back another day.
