Have any of you had a good look at the seats you are using on planes resently? They are for the most cases borderline filthy also in first. So, if germs is the argument don't fly!

Would I care most likely not.

What i would care about would be if I took up space for others, if the lounge were full. Talked loud on my phone. Watched a movie with out head set. Not being verbally polite. Being Intitled....
