When I was asking, I was a $10 calcutta player asking guys who went for higher. I only asked a few times before I got uncomfortable asking because it wasn't just a "no thanks" response. It was more a "where are you from" response.
I look at tourneys as a day out for fun. I expect to spend $ with an outside shot at making some in the tourney. So if I go 2 and out, I lost my entry fee, calcutta fee, $20 bucks on 2 matches, food and drink. The extra lost on the gambling wouldn't make a difference. If I were fortunate to win a few of those matches, it'd pay for my entry fee.
