Nothing too scary or too unusual, but find out who is compliant and who is able to meet "little requests" until they can figure out who will not be likely to complain.
It's a tactic employed by many scam artists are well. I think of it as the "Give 'em an inch, they will take a mile" strategy.
If 'caught' or called on the behavior in the early stages, they can just stand back and say, "I did nothing. This means nothing. Nothing happened. What the @#$$ are you talking about?" etc.
Other criminals use this type of ploy as well, even armed robbers may approach, ask for money or compliance but not initially SHOW the weapon. If countered or caught at this stage it can be very difficult to proved the scope of the crime and it might even be impossible (or impractical) to show ANY crime was committed enough to get a conviction.
And to be fair, such criminals are PURPOSELY IMITATING well-meaning, caring, and helpful people who have no bad intentions at all.
