As others have pointed out, 14.1 is not the same as every other game. It's 14 and 1 continuous pocket billiards. Not rack, run and re-rack. Disturbing the balls in 14.1 affects the game too much to assess a one-rack penalty and then continuing.
In these two hypothetical cases, I would DQ him from the entire event and not invite him back.
First part is dead on...
Second part... Be reasonable.
You don't nuke the top player, who is a popular draw, and who is generally well-behaved,
over a single outburst. The whole event has only 4 players.
You ruin the entire event to just dismiss 25% of the field over a hissy fit.
Darren's punishment was perfect... there were no more outbursts from him that day.
And I bet there are no more in future events, at least ones involving ken.
