Can I have a cup of coffee please?
Sure. What size would you like? Here are cup sizes.
Uhm, I want to take a large one with sugar, please.
Alright. Anything else? How about soft drinks?
No. Erm, those cream cakes look really good. I'll take one.
OK. That's $2.18 for the coffee and $1.50 for the cake.
Here's $5. Keep the change.
Thanks.
