There are four check-in counters open, and a line in each one, so I pick one and wait for over half an hour. When there is only one person left in front of me (and it is 1:00, my flight is at 1:55), the guy working in the counter says his shift is over and closes the counter, leaving a long line of people there, without options. We start to protest, because there is no way we would wait for another half an hour (I would have miss my flight, since check-in closes 40 minutes before the flight), first we are ignored and finally the other three counters start taking one person from our line, and one from their lines (among the protests of the people in the other lines, which I completely understand).
Since I was the second, I could check in and left before the protests were bigger, so I don't know what happened next (I didn't have time to stay and file a complaint). I think I may try to file a complaint now.
Anyway, I don't understand why, if the guy know he has to leave at 1, they don't tell some time before to the people to stop waiting in that line. It is not the guy's fault, since if his shift was over, I understand he had to leave, but they should be prepared for it, and have a substitute or close the line earlier. I guess that's what you get for flying so cheaply...
