Cafes and Coffee Shops by Jmill42
Upon your arrival at a cafe, you are expected to pay at the cashier's desk (cassa) before consuming. Check out what you want, then pay. After that take your reciept and head to the bar, placing a small denomination coin on your receipt (scontrino) will get the bartender?s attention.
If you would prefer to sit down and take your coffe, it will cost you at least double, in my experience. Doing this, you do not need to pay first. Just sit down and the waiter will eventually come over to take your order.
