When you order an espresso or snack, if you don’t want to pay the coperto (service charge) then don’t sit down at a table. Once you sit, you are charged the fee. If you drink the coffee and eat your snack at the bar (this is common and you will see locals doing it all the time), you’ll avoid the coperto (which is typically €2 per person).
