Something like 16% of air rage events arise from disputes over passenger seating arrangements, and it's usually because the person(s) causing the problem have expectations that their every wish and demand will be catered to 'like royalty'.
Sound depressingly familiar with the idiot Qatari Sheikh's recent behaviour, with fractional's reported mid-80's episode involving another 'affronted' idiot Qatari Sheikh, and with scan(cubed)'s report of the Omani idiot's criminal assault of a CA with a camel whip?
Simple remedy for behaviour like that.................red card (mandatory send off) plus 5 years jail for the idiot if assault's involved. End of story.
