Leftover expensive dessert

There is always a lefover dessert in every restaurant, normally those dessert that are on buffet cannot keep for the next day service and its normally go to the garbages. Normally everything from the buffet are go direct to the garbages because these cannot be used anymore. I felt so bad when i see so much wasted food like this.

Do you know that this dessert cost 40aed, 400pesos,10USD each glass in my hotel. This is very expensive.Yes this is taste so good but if its this expensive i will not buy this. The good thing is I can eat it for free.
