Worked in a pet shop for many years that sold everything but dogs and cats.
any non venomous snake there was was there at one time or another along with Monitor lizards and everything. I once pulled out a baby burmese python for a customer, nasty little bastard lol, struck at the customers face, and then hit me twice in my forarm before I could blink......so back in the cage for him lol.
We had a friend that raised snakes, and in his venemous room, WOW that was eerie go in there and hear rattlers, hisses and all.
Notice I said had, he had a lovely black cobra and she was egg bound and she was out on the floor, he had handled this snake thousands of times was quite tame (if you can believe that) and he was giving her an injection to help her relese the eggs, and in an instant she struck, he was wearing sandals, and it hit just right, right at an vein by the big toe.
He did not have time to get the anti-venom, and his wife was a nurse, all she could do is hold him till he died.
So leave the venomous snakes alone !!.
