Hi, I have been given a copy of this game by a friend - however they don't have the instructions any more!! I am trying to figure out what all the symbols in the guest list mean i.e burger = hunger, drinks = thirst, I am assuming lower the number the more hungry? But what is the lightning bolt etc? Anything else you can tell me would be greatly appreciated! I'm stuck on the city zoo as I can't keep the guests happy enough.
