Let me be the first to say that responses like this are a quick way to a walk toward the exit sign. I'm going to say in the most professional way possible that disrespecting the staff here will do you absolutely no good.
btw, many people are seriously afraid of snakes of all kinds. It's not the same as being afraid of a dog as you expect to see dogs at the park. Keep the snakes at home or save the day trips for an educational show maybe.
