#Person1#: Can you help me figure out how to use this vending machine? 
#Person2#: Yes, I would be happy to help. What do you want to buy? 
#Person1#: I want to buy that candy. 
#Person2#: OK. So this machine will make change if you need it. Do you have your dollars ready? 
#Person1#: Yeah, so far, so good. 
#Person2#: Next, you feed your dollars into the machine in the slot. Make sure they are smooth. 
#Person1#: Yeah, I already knew that. 
#Person2#: I'm sure you know that if the dollar gets stuck, you might have to re-feed it. 
#Person1#: OK, let's move on! 
#Person2#: Now you just make your selection and pray. If nothing comes out, try again or call the number on the side of the machine. 
#Person1#: I hope it works! 
#Person2#: Well, good luck!
