Safety pee
You are missing the point..the crew weren't fit for duty..french tv had a program which interviewed the sight seeing chopper pilot who flew them on the day of their departure when they should have been resting. Most of what you have written was normal in a decent company with professional aircrew.
I flew the route for six years with the first carrier that flew directly from northern Europe.
The crew were a disgrace especially the captain who thought it was a good idea to flirt with his crumpet ; the senior copilot was doing a 90 day recently trip..management ..mostly it was hard work flying with managers because often they weren't good pilots.
