I have a hobby as a photographer that while enjoyable, is far from rewarding financially (not a complain, I don't chase money from it). Many people offer promotion and 'exposure dollars', as coined so expertly by The Oatmeal.

So what I'm proposing is to follow this ethos, and try to pass on whatever cheap gesture your bosses throw your way into the rest of your life.
Offer a slice of pizza from that pizza party as part payment of your rent, a clipart laden letter of thanks to your mechanic, trite motivational posters to the tax department.
Please share the results here for the lols, but more importantly with your management so they may get an idea of how useless it is to your life, instead of a livable wage and conditions.
