The thing that scares most people about snakes in my experience is not that they will bite them (this is the answer they give but not actually the scary part when questioned) it is the way they move the absolute still ness snakes have little to no movement and then super speed. I usually just get them to watch nigh explorations of the snake safely behind glass. The key is patience pulling a snake out and thrusting it at them is more likely to traumatize that person than anything. As already suggested patience is what is needed quiet and gentle understanding often makes for better encounters. Of course a snake can bite and eventually you will get bitten it happens. The experience is often startling but nothing more a little scratch. I often point out dogs dental hardware when you get truly (not a nip but a true bite) it is a serious occasion. I got 22 stitches and one hell of a bruise when it happened to me.
