I can understand where you're coming from but it's neither the fault of the flight attendants nor the cleaning crew that your country has such shitty regulations, but they're the only people who will suffer from your protest...
That's the "they are just doing their job" cop-out. If they aren't happy with the consequences of working for an organization that denies people their basic human dignities, then they should be looking for a new job. To give them a pass because they are just little people in the machinery of a big faceless organization is to give the big faceless organization a pass.
No, you can punish the big faceless organisation by not purchasing tickets from them in the first place, but urinating on the floor of the plane will only punish the FAs who already have a very hard and sometimes dangerous job, and might not be in a position to "look for a new job".
The cop-out is you claiming that you can treat people in such a disgusting manner because of your assumption that they're able find a less degrading job at their whim.
