I sometimes watch re-runs of the old Airline series and it makes me laugh how stroppy people get if they can't get on their chosen flight because they were late. Put a TV camera in an airport and normal rational people turn into raving loonies. I feel sorry for the staff having to endure this, but at the end of the day, they have been there waiting for YOU, they have the aircraft ready and waiting for YOU, if you can't turn up on time, its your fault.
Next time, try and turn up on time, that sounds harsh, but its the truth
