The quickest way to get your spot back: flattery. "Wow, it's hard to believe that a peak physical performer like you would even /need/ a bench! A lowly weakling like me could really use a place to sit, especially after such a thorough ass-kicking!" Works every time! Uh, I'd imagine…

Sheldon may look scrawny but he's a wolverine if you take his spot. Bazinga!

Darn those little old ladies!

Did you refuse to give it up? Then you also seem to be one of those people who will fight for "their" spot.

Assuming the person isn't elderly, disabled, or pregnant, OP is perfectly entitled to not giving up their seat.

(fyi replying to replies doesn't work, you have to reply to the original comment)

There's nothing in this FML to suggest that OP was bullied in any way beforehand. And even if the person did threaten them, it's not like anyone would be expected to follow through with such a threat.

muscle beach... literally.

SUE HIM.
