A dunkin donuts customer can't ride a bike very far and needs the bus anyhow. A real commuter can ride tons of miles without use of the bus! There is a car commercial I have seen running around where a european cyclist is on the left hand side using a car to keep him balanced at every stop. Eventually the car driver gets fed up and goes in reverse (in reality he would have hit someone from behind because of traffic ;0) However the cyclist put his hand down and the car wasn't there so he fell. I was kinda mad for a bit but found it slightly humerous. We just need to choose our battles.
Remember the best place is to just hit them in the wallet.. just don't go there or buy their donuts.
Keep Cycling,
Jeff
