D: I would mercilessly pwn them by ridiculing their physique and lifts.
that is freaking hilarious...
Anyways to answer your question, I would have at least offered my seat. I ALSO would have embarrassed the dudes at the bar who wouldn't give them up.
Back in my "bouncer" days I would carry eye drops (regular "get the red out" type) and when I encountered a jerk (rude before he was drinking, woman "handlers" ect..), I bought him a drink...added about 3-5 drops and left with a smile and the knowledge that he was about to have the most wicked diarrhea and cramps he has ever experienced. Had one guy shit his pants later that night...guess he thought he could fight it.
