Here's a neat story. My daughter is a cosmotologist. She gives soldiers a hair cut (free) all the time on barracks instead of them going somewhere else. They always give her money because the going rate is $5 per haircut (they give her at least 7-8 dollars per cut, they need a cut about once per week depending on how their hair grows), and she does it right in their rooms. She's been saving up her haircut money, plus tips, and is planing on buying the guys a tv and dvd player. PS, don't tell them...
Wonderful story!
