"I'm a flight attendant....
So many incidents occur on the plane that every day passengers don't see or consider. My last flight an elderly man accidentally sh#t on the floor, stepped in it, and walked on like it was nothing. DO NOT WALK AROUND BAREFOOT. Pee and poop happens, all over. I feel like I witness an "accident" regularly; in their seat or in the lav. People get nose bleeds, or their wounds open. Obviously when we land, it is thoroughly cleaned. But inflight our resources are limited.
DON'T CHANGE YOUR BABY'S DIAPER ON THE TRAY TABLE. This also happens all the time. It's unsanitary and people use the tray table to eat, put their personal things on, etc.
Lastly, it is NOT the responsibility of a flight attendant to lift >your< bag. There are multiple injuries caused from flight attendants lifting heavy bags to be friendly, and then they're out of the job for months to a year (on average). If you pack it, you lift it. If it's too heavy for you, it's too heavy for us.
Happy flying, ya'll!"
