Unsafe snake handling?

[Bel5191]

Hi all,
I don't know if anyone has seen videos on YouTube posted by viperkeeper or not. He has pretty much all the most dangerous hots and has a lot of videos handling or feeding his snakes.

My question is, for example in his one vid, he is giving water to a new wild black mamba with a squirt bottle. And he actually states in the video that he's in the strike range but that the snake isn't interested in biting him.

I'm sure you keepers that have hots can read your snakes pretty well, but do you ever put yourself in that position? I mean the one time you think that you have it all under control the snake could decide that was the day it would go crazy. It seems irresponsible to me but I was just curious.
