Personally I see this as more as a half full, half empty situation. One can start with an assumption crews are hostile to passenger and upon see this this activity, it will re-enforce that opinion. Or one can assume most employees are not hostile (IME), and this situation become potential misunderstood or the rare acts of a rogue employee.

I don't know the answer. but human nature will lead to two people to see the same situation and draw very different conclusions. Hence my statement earlier about optics, without a clearer clarification of those situations passenger will reach different conclusions. And it reality it is unlikely these are 100% valid cases or 100% fake cases. But as a bladder challenged individual (approaching my 2 MM flight) I fortunately have rarely come across out of service lavs, hope my charm continues.
