I'm sure all parties were actors.... I have a relative with a film degree and in the reality tv biz....
He always said... " if you can hear the person on video, then they've been wired for sound. That means the encounter was prearranged and therefore not spontaneous"
I have to disagree.
In a studio type setting wiring “the Talent” has several disadvantages & few advantages. There are better ways.
Mics can be seen.
Fabric rustle is a problem.
Wind (directly & indirectly blowing fabric)
Balancing several different mics for the same audio level.
Cabling or needing discreet radio frequencies for every mic.
& so on.
Most movies, tv shows & “reality” sets use “Sound boom operators” because they get good sound with none of those problems.
“Wiring” is better for clandestine sting operations & so on because its way more “discreet” than a big, hairy guy waving a 15’ fiberglass pole with something resembling a dead animal on it just “out of shot”!
Mic design nowadays is good enough that with a small, controlled stage like that you can get very good sound with emplaced mics.
Having said that I have no doubt the "customers" were every bit as genuine & legitimate as everything else in that farce.
