Two actors test the public.
Social experiments are always interesting to watch because you see genuine reactions from people in awkward or uncomfortable situations.
The latest one doing the rounds online is a "groping social experiment" where a guy and a girl, both actors, gauge the public reaction to a man creeping on a girl on the Tube.
The guy starts off by touching her hand and then he takes it way too far as the girl clearly asks him to stop, watch how the bystanders react.
