Interactable Areas For Guests

[Nabroc]

I was at the zoo yesterday (oregon zoo), and I was at the giraffe's enclosure and there was an opportunity to feed it lettuce for a small fee. I easily made the decision that I wanted to feed it. When I got home I started thinking that maybe this kind of thing can be implemented in to the game as a way to make your guests happier and to earn a small amount of extra income for your zoo. Maybe add some petting zoos or areas to scrub the rhinoceros. I don't know, I just think it may be a cool feature to add.
