 Step 1 
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!

 Step 2 
A: I've never seen a machine like this before and need some help.  B: Sure, no problem. What are you trying to get?  A: I want to buy a drink.  B: OK. This machine needs you to use that change machine first to get correct change.   A: I've got the correct change already.  B: First you put your money in the dollar slot or the coin slot. The dollars have to be smooth.  A: OK, what next?  B: Just know that sometimes the money doesn't go in perfectly the first time and you have to try again.  A: OK, next?   B: Choose what you want and push the button. Sometimes it takes a couple of tries.  A: I agree with you.  B: Hope that works for you!

 Step 3 
A: I want to know how to buy something from this machine.  B: Yeah, the new ones can be tricky. What are you trying to buy?  A: I want to buy one of those snack things.  B: Are you ready to go?  A: I'm clear so far.  B: The money goes in the slot over there. It has to be smooth to go in.  A: It won't go in!  B: Just remember that you might have to feed the money in a couple of times to get it to work.  A: Yes, next step.  B: Make your selection and hope for the best. Vending machines aren't all that reliable.  A: They're totally unreliable.  B: You seem to have it down. Have a good day!
