Am I out to lunch on this?

A player at my game decided to have a tournament at his house for the first time. When the smoke cleared there were four people left with three being paid. I was knocked out fifth so I have no vested interest but I watch it unfold. After the bubble boy got knocked out the host asked if the people in the money wanted for give the bubble $20.00 each. One of the players said the time to ask was before the bubble burst and it was not fair to ask him to give $20.00 to someone when there was no possible benefit to him (as the cashing player). When the host complained to me that the players were cheap, I said that he asked at the wrong time, and they did nothing wrong. He then sent out an invite to his next tournament with a line saying that we would have to discuss the bubble before we start because some people obviously do not understand the concept.

Am I wrong? Is ok to ask to kick something to the bubble when the bubble has already been broken?
I now have those two players who are regulars at my game saying if he is there, they will walk out as they know they are right and they feel they have had their integrity questioned. Also, the bubble boy was a friend of his and they wonder if they went out would he have said the same thing.
