A few that mostly pertain to working with animals: When you're working in an animal contact area and you politely tell people the 3 things we ask them not to do, then as soon as they get inside they break every single rule and then some. When kids are so misbehaved towards the animals you have to step in and rescue the animal. Pertaining to both above: When you reprimand the kids and rescue the animal, and then the parents or whoever gets mad at you for doing your job. People acting like they know everything about the animal to their companions, and you have to bite your tongue as everything they say is wrong. The utter disrespect for "area closed" signs, and the large majority of people who don't read signs. The people who automatically assume any person in the exhibit with an animal is feeding it. Biggest pet peeve: the constant question of "does it bite?" whenever I'm working with an animal. Answer is yes people, it has a mouth! Yet many people assume that since it's wild (or non-domesticated at least) the animal tries to hurt you on a regular basis. Large carnivores aside, most animals would rather not bite you and won't unless you do something stupid. That said there is the occasional jerk that seems to enjoy biting you, and I've known a couple. Also people that try to sneak their emotional support animals past you because they know they aren't allowed, and act all entitled when you confront them about it. I seriously think the little dog would much rather be at home than stuck in a small dark bag any day.
