A: Can you help me figure out how to use this machine?
B: Yes, I would be happy to help. What do you want to buy?
A: I want to buy that candy.
B: OK. So this machine will make change if you need it. Do you have your dollars ready?
A: Yeah, so far, so good.
B: Next, you feed your dollars into the machine in the slot. Make sure they are smooth.
A: Yeah, I already knew that.
B: I’m sure you know that if the dollar gets stuck, you might have to re-feed it.
A: OK, let’s move on!
B: Now you just make your selection and pray. If nothing comes out, try again or call the number on the side of the machine.
A: I hope it works!
B: Well, good luck!
