Some cunning people have their hands full, thanks to their presence of mind, trickery and a dash of good luck. They thrive on cheating which they call a shrewd business sense. Gaston is a shrewd, calculating business minded and opportunist who with his presence of mind outwits as smart woman and makes a handsome profit of a hundred thousand francs from a property even before becoming its owner. Gaston sold the villa to Mrs. Al smith for three thousand francs without making any effort. His presence of mind and his insight into Al smiths psychology helped him making a deal before becoming the real owner of the villa. We should be cautious about such type of people and before dealing them, we should properly investigate about them. They throw trap and often simple and innocent people become prey of their cunin gness. In the name of business they play the game of cheating and fill their pocket with money.
