1. You’re coffee ignorant.
You don’t know when to order what, or how and where to drink it. Coffee culture here is strong, just like the espresso. In most places you pay the cashier first and then present your ticket to the barista. Then you shoot the scalding hot liquid down your throat and leave a few cents on the bar for a tip.
Faux pas number one is ordering a cappuccino after lunch, or even after 11:00am. Also, ordering a macchiato (literally espresso “stained” with steamed milk) and hoping for espresso drowned in a cup of extra-hot milk with caramel on top is a sure sign you’re still a tourist…and that you need to end your love affair with Starbucks.
