I would never put my stuff under the seat in front of me, if I want to stick my bag and coat in the bin, get over it. I am not having someone spill their drink on their lap, wet themselves, puke, or somehow let any fluids come close to dripping or pouring on my bag or coat.

Have you ever tracked into an airport or a/c bathroom where the floor is soaked, and people put their feet in the space you all expect people to put their coats?! No thanks!

If I get on the plane last, and there is no room for my rolling bag because some teenage girl put her roller, purse, laptop bag, 3 shopping bags in the overhead bin - oh well for me! I will have the FA check my roller and FIND room to stuff my laptop bag.

I would never expect someone else to care about my needs, what kind of crap is that.
