Correct pentazepam - there are valid reasons for the big stack and the short stack to delay play in and around the bubble. Anyone who claims otherwise is being contrary for the sake of it. If you have played for an hour and a half and have run bad, been low stacked the entire time, making a minimum cash under the circumstances is gratifying, even rewarding.
Frankly, its silly to claim otherwise as we have all been in such a situation.
On the other hand, there are some sites with a unique culture that seemed to have developed a rancorous attitude where people deliberately run the clock down to annoy other players from the first hand onwards. That's an entirely different matter and one which is grating.
