Comforts of a bus ride

The other day on the bus we witnessed quite a usual for the location, but still a bit disturbing (somewhere in the backgrounds of the common sense) situation. There was this dude who decided to make himself at home right there and then.As usual the people around took it in as something quite in the line of the ordinary, but the poor fellow in front of the relaxing passenger - though at first he tried to nonchalantly look outta the window, - in the long run started smelling something fishy and even feeling some pangs of what he probably at first thought to be those of conscience, but in time gathered it to be the touch of the stale toenails.
He stared at the people around him in disbelief as if asking them to be witnesses of an injustice, looked at the feet in question, exchange a couple of muffled words with his buddy, BUT said not a single word to alleviate his sorry situation, and the rest of the ride was sitting as stiff as a pole trying not to lean against the back of his seat.

The question here is what I would have done? What would you do? As a laowai who knows not the rules of appropriate and amiable behavior (involving maximum personal discomfort and desire not to make any move at any cost) I would have at least help the dude to wake up and teach him a lesson in manners in my broken and funny Chinese, to which the guy would have replied "Oh, he speaks our language quite well", not giving a single reference to the situation, but he has his face to save. And yeah, I am that bad. And inefficient, because little would have changed in the behavioral patterns of that individual human entity...

Putting their feet up is a trend among the people here, and they know what they are doing. Once in Hainan island we were on a route bus and a guy sitting by the window put his foot up on a rail - the seat near him was empty and his leg took almost all the space in the small two-seat section. I looked on as a lady came up and for the lack of other available seats had to sit near the guy. As a real gentleman he of course took his foot off the rail. After all that's exactly what any real gentleman would do at the approach of a lady... The contrast between a barefoot peasant with calloused soles and a well-dressed tourist seemed to be nicely balanced by this gallant act - and just in time - because as a real weathered gentleman the cavalier couldn't keep his foot up in the immediate proximity of a dame, that is why he raised his other foot - the one farther from his accidental companion. It was only then that the universal balance was struck to a tee, and everybody rode on jollily - the guy having leveled up his face, the lady perched on the edge of a chair, and the whole bus chit-chatting in the most content manner possible.

And I not judging anybody, just a snapshot of reality - and I want to improve nobody but myself.
