I'm totally with Galleywench on this one, I don't think it is on to wake people who are in deep sleep, be it to offer them a meal or ask them to put their seat back upright. They may have travelled a lot longer than some others - hence the deep sleep.
If the person concerned was wide awake I - and most F/As would have no hesitation in meeting your request. How would you have been if the boot was on the other foot?, probably throwing your toys out of the cot then too!
Most F/As love their jobs and dealing with customer tantrums is all part of it. I have seen it all before, I even had a gentleman on one of our charters refuse all service on a return flight from Egypt to the UK (5 1/2 hrs) just because he could not have an extra legroom seat - even resorting to calling the purser a silly cow because she could not reseat him as the flight was fully booked with 189. Just think of all of what all that uneccesary pent up anger can do to someone for 5hrs plus.
As to questioning "Why do people become F/As?", we do it because most of us care, and can assess the needs of most/all people in the most balanced and resorcefull way we can - usual solutions come from weighing up which way is likely to cause most bad feeling. However trying to be understanding and as helpful as I always try to be - some peoples attitude to crew and other customers can be more than a little testing.
If all customers tried to have respect for others (including crew) with greater needs than themselves and stop being so childish and selfish, then maybe we would not have so many bust ups in flight.
Ever heard of the saying "cutting off one's nose to spite one's own face".
I understand your point of view, but trying to take out your anger on cabin crew is not the way, I think you need to chill out more and try to think of more positive ways of dealing with such situations.
Unfortunately Economy Class is not a joyride with any airlines these days - and that has to be borne in mind whenever one books Economy/Charter/No-frills.
