I agree BUT I do think context is everything. If they received multiple warnings and depending on the severity of what they were doing, I can see this kind of rage come out. Pressure on the set is high without a pandemic, and I've seen people get sh-t on for less. Not saying it's right, but it's human nature.
The theater chains would have invested in streaming if movies was actually their business - sadly, overpriced popcorn and hotdogs is their business.
