Yes, I agree with everyone, tongs are going to keep you from getting bit! (Ouch!)

But I think that unless your snake is not eating live then I don't think they are being that "picky". Either the person feeding isn't being patient enough, or maybe the snake just doesn't want to eat. Snakes are hunters and eat live in the wild so I think we are the ones being "picky" and making them eat dead. Yes it's convenient but when suddenly they won't eat f/t we call them picky and get frustrated with THEM when they are probably frustrated with US ...

Anyway, yes, your video was very good and you are correct that patience and love is the key.
