Not to be rude or offensive but have you ever heard of someone called Mr. Obvious? I can't speak for everyone but I'm pretty sure that this is where common sense kicks in.. I'm not sure of other airlines but as for the old US common sense, professionalism, and situational awareness were pretty much a standard requirement for getting a second interview. "Leading by example" boy weren't those the days!
And the saying that common sense isn't all that common also applies. I believe we ALL experience that every time we fly.
The sharpie "informational" notes all over the aircraft are becoming a bit over done. I was on an A330 that had flush written and an arrow drawn to the flush button in all the main cabin lavatories. Then I saw the tail number written on the aircraft door, above the aircraft door, the lav wall, the galley wall, the outside HHD compartment door and on the inside of the HHD compartment door. Call me crazy but isn't that just a bit too much? When in doubt can't one just call or go up front and look at the CML to get that info?
When it comes to damaged HHDs I do believe the company had figured a certain amount of damaged or inop units would occur. It now seems as if they were unprepared for the large number that actually occurred. Much like Monitor and Challenge they have underestimated how difficult it is to change years of habit. I fear what people will do when US go cashless.
