After my workout today I wanted to get a snacked to keep my energy up; so I decided to go to the row of vending machines that the gym keeps outside the locker rooms. It's usually a hard decision when I get there, there is so many choices of healthy snacks. I searched the rows of energy bars and veggie snacks to find what would give me the biggest boost after my exercise. I made my choice and reached for the change in my bag so I could pay for my taste treat. I put my coins into the slot in the machine until I had enough to buy my snack. I punched in the number of my selection so the machine could do its work. The coil started to spin until my energy bar fell from its slot. I pushed through the flap to retrieve my bar and started to eat. 
Question: Why did they want to get something out of the vending machine?
They wanted something to keep their energy up
