People use shills for a lot of reasons.

Even shit like this for example a very small time jerk off owns a hot dog stand in an out of the way place. He is not selling any hot dogs because he uses east river water to cook them. Then he gets his out of work friend to come down to his out door stand. That person makes out he is going to buy a hot dog.

Then finally I another guy see's it and decides he wants to actually buy
A hot dog. Then he is amazed this is the best hot dog he has ever had in his whole life. The secret is the dirty east river water.

Someone else sees two people waiting to get another hot dog. Then that person try's a hot dog, and thinks holy shit this is the best thing since bullets.

By the next day through word of mouth their is a mob of people at his stand buying his east river hotdogs.

Now he does not need his friend to be his shill any more.

The hot dog owner his happy. He is finally making some real money for the first time in his life. He doesn't have to live with mommy and daddy any more.

So now he opens up another hot dog stand and hires an employee. Maybe the shill that helped him.

Then he opens 20 stands.

Then he opens a franchise operation called East River Hotdogs. Later they spring up all over America, south America and Europe.

Now the owner has 5 mansions all over the World. He owns his own jet, has a load of high end pussy, and he lives happily ever after all because of a shill and east river dirty water.
