Looks like the film maker was doing his best to acquire evidence for a lawsuit-including baiting tactics. She will lose her job and there will be a ‘settlement.’ Cameraman wins.
She was being unprofessional and lost her temper and got vulgar...but the cameraman was intentionally provoking her in order to get her that way, so he’s got no reason to fuss.
Yes, I see this as a set-up.
Diners provoking the waitress relentlessly and then filming the part where the waitress losses it.
Cash cow.
