Simon,
We are not discussing women speaking to women, but a man asking to speak to a 15-year-old girl. There is a problem with asking to speak with a 15-year-old girl. Such a person should ask to speak with the head of the household.
Because of what he did, slapping the woman or hitting the camera, law enforcement is involved. They have probably conducted a background check on him. Suggestions made here can be a protection.
