Funnily enough, the reason why I stopped buying cakes and pastries was because you can rarely get 'one portion' sized buns separately, so either you get more and have to throw a few in the waste (because they are at their tastiest on day of purchase) or you be a pig and eat them all. Fatties are so used to their sunk cost fallacy of "can't let this go to waste I paid money for it" that they have normalised eating a whole fucking box of cakes in one sitting.
