I work in a library that has very old vending machines in the basement. Today however, we got new space age vending machines. What makes them space age is that they have a much larger selection of items than our old machines. They're refrigerated so they have sandwiches and pickles and items such as that. Another thing that makes them space age is that they take credit cards as well as cash. Today I don't have cash, so I get to go down to the vending machine with my card. I swipe the card and it tells me my card is accepted. Then I choose my item. Peanut M&M's. It's always peanut M&M's. I put in the letter and number of the item. The machine thinks about it for a second then drops my item. I bend over and push open the door at the bottom. I retrieve my candy and skip away.
What other kind of vending machine was mentioned?
