Nancy Armitage was once visiting Thailand when a local grifter threw a python around her neck and demanded money to remove it. Nancy, an avid ophiophilist (she had her own snake named Floyd at home, and used to catch venomous snakes for fun), intuited that the snake was relaxed and posed no threat, so she calmly demurred and walked away, leaving the stunned scammer to run after her to get his snake back.
