Our broker/financial professionals taught us the "rules" of RAK years ago, and I have found the hardest to do is pay for someone else's lunch, gasoline, etc. as it is to be done without their knowledge as to has paid. It is fun, to work this out. Also, when you give somehting to a child, tell them to do "something nice" for someone else--of course, not revealing anything. Don and Ryan have the server, or other intermediator, leave his printed card stating the "reason" and the recipient is to use that same card in his/her next action.
