While, yes, there are many of our co-workers who say no just because they don't want to go through the trouble, the rest of us are merely following procedure. So, please don't try to bash those that follow our safety procedures by using the "lazy" excuse. We are trained NOT to take any food, liquids, or personal items, (besides coats in the closet) into our possession or store in any compartment or galley space. So, while you may be providing customers an extra service, please realise that your assumption of why others aren't doing the same thing is off-base.
