A Buck
Speak as Erin
Speak as Angela
Angela: Sure. What do you need it for?
Erin: I want to get a soda from the vending machine.
Angela: Here are two bucks. Can you get me a Coca-Cola?
Erin: No problem. What if they are out of Coke?
Angela: In that case, get me a Sprite.
Erin: I'll be back in a couple of minutes. The vending machine is on the 1st floor.
Angela: No rush. I'll wait for you here.
