In my salad days I performed in out-of-the-way spaces in Seattle, including the Odd Duck Studio, where an event is happening called, optimistically, PROSTITUTE YOUR GENIUS. I bring this up only because I think I have finally found a practice worse than dinner theatre:
This will be a "Ching Ching & Bling Bling" event, which means that after you have left the stage, the audience will be invited to THROW CHANGE! You keep the money (usually $5.00 or so.) If you want to make more money, bring more people to the show!!!
Times may be hard, things may change for me and my colleagues but I promise you this: if I am ever in a position where I am spare changing on stage, I will simply pack it in and go back to temping.
