Male Inflation

Jeff rolled his eyes at the kids across the store, their giggling and scheming giving them away completely.

The convence store had recently remodeled their soda machine, to prevent theft. Rather than filling your cup and then taking it to the register to pay for it, you now had to insert money directly into the machine before it would allow you to pour a specified amount of soda into whatever container you chose. 

These kids, however, seemed to have purchased a contraption of sorts, to pull the fizzy beverages from the machine regardless of if money was paid.
