There should be no rush in a poker tournament. I too always lose when in a hurry. You need to allocate 3 hours for the game only. Then you can play and enjoy it.

Trust me, the entire week I have nothing much to do. But on the last Sunday I had full house LOL
Relatives came to visit and they have children and you know when there are children you can not do much besides you need to give time to the guests. Fact is it was more important for me to spend the time with the guests than playing poker in the last Sunday.
I don't support it

Since this is a privately paid bounty, the "donator" should be free to have whatever rules he likes to have. If he still wants to give the bounty to a winning player, to donate it to lottery/Grand Final pool, roll it over to next tournament or don't pay nothing in this scenario, should be up to him and not forced by some general rule.
We should be happy that people add more money voluntarily and not "bully" them

The guy who is awarding the bounty has the full right to pick anyone or apply any rule. Who was the other guys last week with me?
