Story idea – kung fu movie

I had an dream about a kung fu movie a month ago after visiting some exhibitions of Bruce Lee and Jin Yong. The main concept was that the characters were in a world where physical disputes are illegal and enforcement is immediate. However, it is possible to bend the rules if the disputes start from an argument over food. So, there are two rival gangs that meet for dinner at a Chinese restaurant and they both are polite and start eating together. Then, at the “signal”, the henchmen throw some food at each other and then the gang fight begins. All the people at the table start fighting besides two people – one person from each gang. They are the designated “eaters”. If the food on the table runs out or if no one is eating, the police will crack down on both gangs. So, the two “eaters” need to ensure that no one is arrested for the fight. If they think that their side is winning, they may want to order more food to ensure the victory. If they think their side is losing, they may want to finish the food quicker so then the fight ceases. The “loser” of the fight not only loses the dispute, but they need to pay the bill for the food and damages.
