Reward Points?
I take my kiddo the movies once in a while and I have a reward card with a local theater here. We haven't been in a while so they put a free popcorn on the card. Sure, we'll go see a movie... I checked to see how many points we had accumulated on our card and there was a loooot. When we talked in there was a family in front of us with six children, if I remember correctly. They ordered a large popcorn and then asked for a few bags (the little brown lunch bags). I talked to my son and we got a popcorn and then used a bunch of points to give the family extra snacks. I love seeing the looks on people's faces when a stranger does something nice for them with no strings attached.
