Whenever you dine at an “all-you-can-eat” buffet, the rational consumption prototype is to carry on eating till: (1) The restaurant goes bankrupt. (2) You have eaten as much food as it would encompass cost had you made your own meal at home. (3) Your subjective assessment is that you have received fair value. (4) You reached the absolute capacity of your stomach. (5) The marginal utility of additional food is zero, after considering taste, calories, and so on.
Please someone suggest me the right answer.
