Myself I don't find it disturbing unless it harms the animals or goes way over the top.
I have known of at least two that bothered me.
1. A young (nameless) lady who carried her snake in a small wicker basket that has a top cover
everywhere she went. Road trip, Take the snake, shopping, take the snake. Her attachment to the snake was quite disturbing. She couldn't go anywhere without that basket.
2. Almost comical, but not really.
This one woman posted that she had gotten bitten on the side of her breast, when I asked how in the heck she got her boobies in the snakes line of fire, she said she put the snake in her shirt so it could find solace in her heartbeat.
Since I was the one who sold her the snake, I felt badly for the poor animal and rather wished I had not sold it to her. Ultimately she was evicted from her apartment and had to give all her snakes to an animal shelter, making me feel even worse yet for contributing to her madness.
Then when these things go horribly wrong, Like a boa or python biting someone in the face because they were "smooching on it" and the media gets hold of the story, the evil snake is always to blame, and our hobby suffers from it.
Honestly, puting your face right up in the snakes face is asking for trouble sooner or later, the snake my put up with it for now, but someday the snake will decide it's had enough, and the end result can get real ugly in a split second.
The snake may one day percieve your face staring directly into (him/her) as a predator moving in for the first bite of its new meal (your snake) and a strong defensive strike will result.
