You have recently started a part-time job, working as a barista at a small coffee shop to fund your student life. It's very quiet - only visited by regulars and those on the daily commute

You're working the afternoon shift when you hear the door open, and someone comes inside. It's one of the regulars - you don't know her name, but she comes a few times a week to study and drink something. She approaches the counter and smiles politely

"Hi! Could I get a um, medium mocha, please?"
