Shopping Roleplay

We've started a new system in our English class. When the students do well in class or tests, we award them with "Dollars" (Sincheon Dollars) - Either $1 or $2. So, we had a shopping role play activity where they could "buy" snacks or stationery from our Restaurant and Market Zone.

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 !!!!!
