It's the minor DYKWIA flyers (yes, you in the suit with the Blackberry blethering at the top of your lung, pushing and shoving their way through to the gate to a seat they did not pay for) that just bring out the worst in everyone - not just Y pax.
I've been flying paid J & F fares (unless I had miles to burn) since I was 16 and had the occasional temptation to kick the a-hole in 1A in the teeth, I don't understand why some think that their fare is a testament to their egos.
Just chill out... no one on this plane needs to know what strategy you think is going to yield a higher return next financial year or if the embroidery hasn't been properly tailored on your shirt.
