Feet on seats!!!

After a long hard day at work, I turn to see this, I had to take a picture of this as I was that incensed!

Aaaaggghhh what is wrong with these people.  Why on earth would you put your dirty shoes on seats meant for sitting?  I have to sit on them, in fact, you completely selfish ignorant commuter - it will be more than likely that you have to sit on them again.    I seriously hope that one day you end up sitting in some foul matter one day, and maybe you'll realise how gross it is to sit on crap from someone else's shoe.

This guy has to be at least 35 years old - you'd have thought he'd have some respect.

Can someone please enlighten me as to why you would this?  I mean, maybe it's me, perhaps I am being pedantic...but would you want to sit on what's on his shoe?  I'm not even getting onto the rant that he is monopolising seats!!
