Depends who you are, I think. Back in the Don Meung airport days, they used to call flights (and tardy passengers) over the tannoy system. Genuinely, my watch stopped half an hour before Gate-Opening and boarding time. Appears they were calling my name but mispronouncing it, so it did not register that it was me they were waiting for. I noticed my watch had stopped and ran to the gate ten minutes before departure. They had already offloaded my suitcase and would not let me board, even though the steps had not yet been wheeled away from the aircraft. I was chagrined and polite and smiling and self-deprecating, in the hope of some leniency. All to no avail. I was obliged to collect my bag, go through customs as if I had just arrived, where they searched it thoroughly. They charged me the (then 300Bt) overstay and stamped my passport with the potentially repercussive black mark of an "overstay".as we were now past midnight and I had to find and pay for a hotel and reschedule (and buy) a new seat for the next evening. Maybe your physical appearance, as opposed to my own, has something to do with how I can sometimes find myself accommodated by bureaucrats that differs to your own typical reception. Haha.Here's the closest image of me I can find...
I agree but it's very short notice and there's a whole Airbus A380's worth of passengers all trying to do the same, which is proving to be a bit of a nightmare vis-a-vis rescheduling.
