You need to get out more.
There you are asking how a poster knew he was in an aircraft at 36,500 ft when everyone knows BA has airshow and now you don't know that BA make an announcement that "The cabin crew are here MAINLY for your safety."
I guess that would make you one of the arrogant posters, wouldn't it? Just what we love...arrogant passengers. Would you care to tell me about how you pay my wage, too?
I spent a fair amount of time riding from A to B as a passenger. I don't believe I've ever been on a British Airways flight, however...hence my query as to what means the poster was using to determine his flight level. He may have been using a handheld GPS, you see...many do...and asking a simple question was necessary in order to know how to best answer his question...without the arrogance you seem to embrace.
Its called providing customer service and it is part of the reason they are on board, if they weren't we pax would travel with another carrier.
Time for you to take another load of rubber dog turds out to HK and leave those of us who spend a lot of time in the cabin who know what we are talking about to reconcile the fact that highly trained and capable crew also serve a customer service function for the majority of the time ALTHOUGH THEY PERFORM MAGNIFICENTLY LIKE THE CREW ON BA038 WHEN NECESSARY
Hmmm...I don't believe I've ever flown "rubber dog turds," though I suppose it's possible. I do get in and out of Hong Kong with some frequency, however.
You are an arrogant one, I'll give you that. I suppose as a passenger you would know much more than a trained, practicing, professional crewmember who's been doing this his entire life...thank you so much for your invaluable experience and insight. What would we do without you? I can't help but feel that our training is remiss without your guidance there to set us all straight. Would you perhaps consider blessing us all with the benefit of your expertise as a passenger to come tell us how to do our jobs? At your convenience, of course.
Services that a flight attendant may provide with respect to passenger comfort are in addition to, and over and above their primary function as safety specialists. The regulatory agencies that require them to be on board, and set specific requirements regarding just how many must be on board, do so based on safety in flight and on the ground. Not on how many crumb cakes can be served per hour or how much coffee might flow through a given size filter...and certainly not on the hemline or length of a skirt.
