I have been using the book The Armchair Economist for a few years in my
classes.

A student who worked in a movie theater suggested that popcorn(and candy,
drinks, etc.) cost more at the movies because the theater has to have many
workers around to handle the rush right before a movie starts. �Then those
workers have nothing to do for a couple of hours but they need to be paid for
the entire time they are there. �It would be too costly for them to go home
and come back every two hours. �So when you buy food there, the extra cost is
for the time workers are getting paid and not doing anything.
