Courting and being in a public place without a chaperone would be ok but you would have to arrive separately or if you went together you would need a chaperone for the trip and they could sit at a separate table.
Or if a witness worked at the public place you were visiting you could pick up your courtin' date and her father would know when she got picked up and the witness working at the public place could call the father to let him know the couple arrived (therefore no messin' around time on the way) and repeat the procedure when they leave (again, no messin' around time).
Sure sure that video was realistic......NOT
I know because I lived it more than once and from different perspectives. Stopping young people from touching each other's parts is a huge part of dub life.
