Ive had this same damm thing happen to me!! It was a just a fat %$# guy taking up half my seat! The only, only, reason I sucked it up was that it was a 30 min flight and I was jumpseating home. But seriously do these people even realize that they are being rude?! I mean seriously you cant just put the arm rest up to get some more room for yourself! Im usally an understanding person, but this guy got my d-bag seal of approval when the FA had to come up to him twice to turn off his PSP before takeoff and he ignored her and then told her that he was almost to a "save point". All the while im in uniform just shaking my head being used as and arm rest for his freaking arm!! sigh...
