You are learning greetings and first words: you will read the scene it happens in, take apart the pattern behind them (ordering formula + basic greetings), hear them in a conversation, rehearse them, and finish by saying one thing out loud to be graded.
A New York City deli or bodega — the corner store that sells everything from coffee to sandwiches to MetroCards. Open 24 hours. This is where New York begins for most people every morning.
The bodega on the corner of 8th Avenue and 28th Street has been open since 4am. It sells coffee, bacon-egg-and-cheese sandwiches, lottery tickets, MetroCards, flowers, and anything else the neighborhood needs before the rest of the city wakes up.
The stranger walks in. The man behind the counter is Egyptian, has been here for eleven years, and has made approximately forty thousand bacon-egg-and-cheese sandwiches. He looks up.
"Good morning!" the stranger says. "I'd like a coffee, please. And a bagel with cream cheese."
The man nods, turns to the machine. "How are you today?" he asks, not looking up.
"Good, thanks. And you?"
"Busy," he says. He hands over the coffee. "Here you go."
"Thank you so much!"
"Have a good one." This means: have a good day. New York shorthand for warmth.
