I personally agree with most of you. If people think, they have to carry heavy luggage than they also have to stow it. They get it out of the house, through the airport on the X-ray....etc.
But i also "refuse" in a nice way....like finding same space in comp.,just holding my hand under it whilst lifting up....etc
What i really hate, is, when i hear from pax "the lady at the gate told me the stewardess will find a place for your luggage". Then i really would like to call this person immediatly.
