Though true, how many times have we sat on a plane while FA repeatedly ask for "if pasenger so-and-so is onboard please press you call button and then a half hour later still sitting at the gate while they pull their luggage off? what a pain in the butt for everyone else....

And to add, there have been a increase of posts on "how can I abuse the flat tire rule"? And I agree that if more people do abuse this benefit for their own personal pleasure, it will be taken away from all of us and then we all lose out when we really need this benefit.
