Italians drink small cups of espresso or moka (if homemade), and maybe a cappuccino at breakfast. The morning and lunch time ones are mandatory, then maybe one mid afternoon or in the evening.

If you happen to see someone having a cappuccino at lunch, or, yikes! with their dinner, they're probably a tourist.

When I last lived there, Starbucks and the lattes and pumpkin spice big mugs were a "weird American novelty" for teens in major city centres.
