Have the stranger discipline the ferret walk him or her through it.  the
best place to go is pet stores allow the workers to hold her and have
then discipline her if she bites, hold her while you let people pet her
and it she makes any mnove to bite remove her discipline her and bring
her back and allow them to pet her, afterward you must give lavish
praises adn treats bring raisns with you.  Show her then stranger need
good things not bad things.  thats what worked for my ferrets they are
now 3 y/o and I can trust them with everyone
 
Hope this helps,
