Ouch! Retic Feeding response question

[Xanafein]

So, I was Feeding The other Day and i had a friend over, My retic was still in her feed box, So i went to go and hook her out, my friend leans over while i open the box (despite countless warnings) Upon Opening the box, My 5 ft dwarf Lunges out of the box and tags her on the cheek After putting her away, I then spent an hour consoling a crying 20 year old telling her that there wouldnt be scarring and her face would stay pretty.

This brings Me to a question that I Probably should have asked a lot sooner.

since Many people Believe that feeding out of the cage for terrestrial snakes helps to improve temperament i was wondering, With a 12' Plus Snake is that even remotely possible?

P.S. I tried to get a picture of her face but she slapped me when i grabbed my camera :|
