No Such Thing as Free Lunch

In Psychology class, we watched a video about people who would go to extreme measures (from pressing a button 5000 times, to bowing down to a machine) to get free Fantastic Delites. But were these really free? Not quite. To get these chips, the participant needed to spend time. From each request of the Fantastic Delite machine, one needed to spend time to accomplish those, therefore, these chips were not free.
