Now you know why it is generally frowned upon to bring our animals into public places outside of an exhibit or show where the public are aware that snakes, etc. will be on display.
An act like the one you did, harmless as it seemed to you at the time, could have provoked a heart attack from a weak elderly person; it's that serious.
Hopefully this doesn't spread to the point where legislation is placed in your area... it has happened before.
