But they had to memorize a dialogue:
Customer: Excuse me?
Shopkeeper: May I help you?
Customer: Yes please, how much is this cookie?
Shopkeeper: It's $2.
Customer: OK, I'll take it...here you are (hand them the money)
Shopkeeper: Here's your change - thank you!
They had a great deal of fun, but... imagine having to say this dialogue OVER and OVER again. My head was sssssspinning !!!!!
