I wanted to put in the comment that if you are very experianced and casual about handling snakes, you can handle snakes with such nonchalance that it appears to be rough.
Knowing how to carefully scoop up a baby ball python properly, and having done it over and over and over, it's very easy for me to reach in and "snatch up" a baby, without harming it, without causing it stress. Unhooking a tail that's wrapped might only take a slight movement of one finger under the snake, but done quickly, it can appear that you just pulled it loose.
I know some folks are rough, but remember that the casual nature of handling of an experianced person can LOOK like they are careless, and the speed that they can pick up and manevour the snake can look rough. But the snake isn't harmed, and isn't even upset, IF it's done correctly.
I understand that snakes poo. They will poo even at a show in the beautiful display. But dried feces smeared around ins everal spots in a container, that's just nasty and should have been cleaned up! How can you sell an animal out of a filthy display?
Stepping on ANY reptile should be unacceptable, Unless it's actively chomping down and injuring someone(which makes it a maybe only).
I feel that hand sanitizer probably isn't greatly effective, but it's better than nothing. I only handle animals I'm genuinely interested in buying, and otherwise try not to touch anything.
I tend to stuff my hands in my pockets when I look at something I really want.. lol. Like the kid at grandma's house, you just know not to touch things... and I don't understand people just grabbing stuff. I DO pick up deli cups to look at animals... but I don't shake them, and I'd never jerk them around.
Kids? Parents should constantly keep them with them, stop this racing around and letting them grab up anything and torment animals. I can't stand to see the little monsters running amock and the parents will get angry if you say ANYTHING about it.
