This thread made me chuckle. A number of years ago I was on a flight from LHR -YYZ. There was a lovely lady next to me and we chatted for much of the flight. On descent into YYZ, after the seatbelt signs were on and the FA's all buckled in as well, she informed me that she suffered from airsickness and proceeded to barf into her bag. She then quickly handed me what seemed at the time to be an almost full bag and proceeded to fill mine as well.

The smell had my stomach churning but my biggest memory is of nursing the bag she'd given me ( the top of which I'd secured with the tabs).One hand gripping the top tightly and the other gently cradling the bag from below. The now warm bag had a soft and pliant feel to it and I was terrified that either a hard landing or sudden air pocket would cause my hand to involuntarily tighten or move vertically and expel the contents.

I was left holding it until we disembarked, at which time I handed it to a pretty ticked off FA at the door, who presumably thought it was mine. Only time I have ever seen them used and I'm cynical that they are big enough because she was not a large lady and the bag seemed pretty full to me.
