Do you tip in Italy?

If you ask locals “Do you tip in Italy?”, they'll explain that while they sometimes leave a small tip, it's generally not necessary. In Italy, gratuity (or una mancia, pronounced oo-nah MAN-chah) is considered a bonus for exceptional service. And it's not often that you'll find a tip jar at a register.
