Airports... eeuughhh!

My flight was at 1.00 pm and I checked in at about 12.00 pm, so I had a bit of time. On the way to the airport I'd realised that I had left my favourite pair of summer trousers behind, and I also still had to call Dain to let him know which flight I was getting. I couldn't get through to Dain, presumably because that was a long distance call, but I got through to Amelia and explained about my trousers and could she also call Dain for me. Done. Oh, before that, I'd gone to StarBucks for a tall mocha frappucino, with whip, in order to get some change. Really, that was the only reason. Then I went and joined the security check queue. A few pages of my book later, I get to the security check and look at my watch, which says 12.45 pm. I just expected that if I was close to missing my flight, they'd call out my name and rush me through or something, I don't know! I finish the security check and walk, very quickly, to my gate (C12), which takes forever, because it is literally the last gate in that direction. It's now about 12.50 pm and the gate door is closed. I smile at the ground staff and show them my boarding pass, they telephone the plane who report that they are closing the doors right now. Sorry. Dang! I remain calm, it's no big deal. Flights on that route leave hourly, so they just book me onto the next one at no cost and I can even get an exit-row seat this time, woohoo! So I take my new boarding pass, get comfortable and proceed to read my book for an hour. It's a very entertaining book, This Side of Paradise, I'm really getting into it. So it wasn't until 1.40 pm that I realised I was still sitting in front of a closed gate and there was hardly anyone else around. Mild panic. Looking at my new boarding pass, my new boarding gate turns out to be N3, not C12. Still too dignified to run, I stride off in search of N3, which turns out to be in another terminal--thus the different letter--and I have to make a quick ride on an automated light-rail car to get there. The car is delayed by several seconds when someone prevents the doors from closing by catching them at the last second, then we're off. I stride over to N3 and find the gate closed. I hand the ground staff my boarding pass but I can't produce a smile. They pick up the telephone and speak to the plane. They let me on. Airports... eeuughhh!
