Octopus

They say octopus will eat his legs or arms(?) when he lost anything to eat.
Sales is not easy, especially try to sell something to unspecified people is not easy, in one of my friend's company, he says the sales is not good. Recently they started to try to sell their products to their employees. Many people are reluctant to buy the one, some buy simply because he wants to help the sales of the products with some excuse themselves like because they are working here or something. But overall reaction is not good. Basically their attitude is the same, -if he wants to buy the one, he buy. But they don't like to be force to buy the one like an obligation or to measure their degree of loyalty. Sometimes the obligatory quantity of purchase is imposed.
Octopus eats his tentacles when he doesn't have anything and hungry, inevitably start eating his legs or arms(?).But he doesn't know yet - when he finished eating all his legs or arms(?), he himself is the one who is going to be eaten, for the first time when he is about to be eaten, he will know he has already lost all his tentacles by which effectively he can protect himself.
