I used most of the 20 dollars to buy food for the people on my floor. Whenever anyone would come into my room I offered them some food, because it was everyones food and not mine. I also spent some of the money at the local bar, buying myself a drink one night. I did this so that people would know that there is nothing wrong with drinking in moderation, and so they would know I did not think any less of anyone who was at the bar.
