I disagree with much of the above post....it IS up to me to establish what I see as reasonable...
Also...whether or not cussing was 'nice' or 'acceptable"....the reaction of the stewardess was the much, much bigger sin in this event...when one has someone kicked off a plane and LE involved because their delicate sensibilities are insulted THEY have the bigger issue not the 'cusser'.
The punishment (as if cabin crew should be allowed to punish anyone much like the TSA) did not fit the 'crime'
