There was a TV show I used to watch called extreme cheapskates. It's about people who will do anything to save a buck. I remember watching one episode where a husband tells his wife he will take her out for icecreme. Then when he gets there, asks the ice cream man for all the free samples and hands it to the wife. There were also instances where I would see people eating at a restaurant and they would ask the surrounding people for their leftovers to take home. I have also seen a guy go to restaurants and ask for ketchup packets to fill up his ketchup bottle at home.
