Interesting question. I always say yes whether big or small stack.
However, I have twice refused to pay the bubble. On one occasion it was because the vehement NO BUBBLE chip leader had the cheek to change his mind after he had his KK re-shove beat by 2nd in chips AA and he became the short stack (GTFO) - we busted him and then laughed, waved etc. TBF I wasn"t the only one saying no at that point, and he wasn"t happy.
The second was when a guy who always refused suddenly in today"s game wanted to agree when he had 2 chips. I pointed out to him that I wasn"t going to let him "have his cake..." and we busted him.
There was an occasion in the Venetian where 16 left 15 paid I was a short stack and the other table wanted to pay the bubble. It"s not a question I raise when I"m a shortie so happy to agree if others are offering. An Israeli guy on my table was very anti and despite pressure from almost everyone he was the only one saying no. Anyway I ended up the bubble and to my total embarrassment four or 5 people got up from various seats and each handed me $20, and wouldn"t let me hand it back. I felt miserable to bubble after 6 hours and even more miserable to be given money in that way. Anyways I took Deb to that noodle place across from the card room with the cash and we had a nice tea on them, fair play.
