Like to add, not as a high-jack.

The main reason casinos want props is because most people don't like to play short-handed games. If the table goes to 6-handed, the game is probably going to break, and it will break once one player leaves. It is better to bring in two props and pay them than lose the rake.

Silent props are necessary because many players do not like playing against props. A silent prop does not reveal what he is, so the players have no idea they are playing a prop. A great way to break a game is to sit three props down at a six-handed game. A silent prop is a good way to circumvent this.

It's all about keeping the fish happy.
