Last year I worked in a local movie theater to earn money during the summer . Part of my job was to clean the theater between showings , collect ing discarded cups , napkins and popcorn tubs . I thought it was odd when my manager asked that I empty and then bring him discarded popcorn tubs that were in fairly good shape . He would then reuse them - refilling them with popcorn for unsuspecting customers . I soon learned that the theater paid for its popcorn concession by the number of tubs it used . By reusing the tubs , the theater was able to lower its costs . However , I was fairly certain that customers would have been upset if they knew what was happening ( I knew that I would be ) . Answer the following questions in detail 1. How would you characterize the practice in which the movie theater engaged ? 2. Should I have followed my manager's orders and gone along with his request ? Was it really such a terrible thing to do ?
