Every night, 10 men met at a resturant for dinner. At the end of the meal, the bill would arrive. They owed $100 for the food that they shared. Every night they lined up in the same order at the cash register. The first four men paid nothing at all. The fifth, grumbling about the unfairness of the situation paid $1. The sixth man, feeling very generous, paid $3. The next three men paid $7, $12, and $18, respectively. The last man was required to pay the remaining balance, $59. He realized that he was forced to pay for not only his own meal, but the unpaid balance left by the first four men.
The 10 men were quite settled into their routine when the resaurant threw them into chaos by announcing that it was cutting its prices. Now dinner for the 10 men would only cost $80. This clearly would not affect the first four men. They still ate for free. The fifth and sixth men both claimed their piece of the $20 right away. The fifth decided to eliminate his $1 contribution. The sixth pitched in only $2. The seventh man deducted $2 from his usual payment and paid $5. The eighth man paid $9. The ninth man paid $12, leaving the last man with a bill of $52.
Outside of the restaurant the men begain to compare their savings, and angry outbusrts began to erupt. The sixth man yelled, "I only got $1 out of the $20, and he got $7," pointing at the last man. The fifth man joined in. "Yeah! I only got $1 too. It is unfair that he got seven times more than me." The seventh man cried, "Why should he get $7 back when I only got $2?" The nine men formed an outraged mob, surrounding the 10th man. The first four men followed the lead of the others: "We didn't get any of the $20. Where is our share?" The nine angry men carried the 10th man up to the top fo a hill and lynched him.
The next night, the nine remaining men met at the restaurant for dinner. But when the bill came, there was no one to pay it.
