I had never thought much about the refillable popcorn buckets that some movie theaters offer.  After all, one bucket of popcorn would be more than enough for me during a movie.  But the other day, I was eating lunch in a strip mall next to a movie theater.  And I kept seeing people going past with their popcorn buckets only to return a few minutes later with it full of popcorn.  Then it dawned on me.  These people worked in the strip mall and were going to the movie theater for free popcorn.  YES!
