If you were on a bus...

And you have a window seat, and some geezer comes and sits beside you (i fucking hate this) then, you reach your stop and do that strange bus spasm to indicate the aisle seated person has to get up to let you out, but, he doesnt move, he just stares at you, even when you muster up the courage to ask him to move, he continues to stare at you, the seats in front and behind you are filled with people watching. Do you miss your stop out of the sheer awkwardness of the situation or do you hit him? Do you cry? What would you do?

I'm not going to miss my stop just because of some old wrinkled fuck not moving. Just move around him, it's not like he's blocking everything. I'm sure there's a little space in front of his seat so you can squeeze yourself through.

I would just ask him again to move:
"Can you please move so that I can get off?"

If he doesn't answer, just ask louder, without the please. At this point, no need to be polite.

If he still doesn't answer, just go through him, who cares if you push him off the seat.

I do the little bus jig and they usually move. Should that fail, I ask them to move. I have to nudge some senile passengers when they don't hear me. The last step that I had to resort to only once is to kick the old man in the fucking head.

But you know what is even worse than old vets sitting next to you? Fat old ladies. She'll take the seat next to you even though there are free double seats everywhere. And she will sit straight in the middle with no effort to contain her blubber. You might press against the window in order not to touch the oldfat, but she will give no fuck and just happily intrude your seatspace, all while having that angry fatman's face.

I'm pretty agile so I just climb the fuck over

punch him in the back of the face. . . with your foot
( after flaming at him)
never miss your stop.
