This is kind of off original topic, since I think people acting like that to gate agents is horrible, but I have to say I'm pretty friggin annoyed that all of the responsibility seems to be on the passengers now a days. There was a time when if a delay like this happened, the airlines would get as many booked and out the door as soon as possible, and do everything they could for the remaining passengers. Now, you're just **** out of luck because you didn't plan ahead correctly.
There's very little accountability on the airlines anymore, and that's a shame. Between the people like the one in video who make the entire experience an "us against them" mentality for all of the employees, and the absolute disregard for any kind of customer care by many of the airlines, long trips just aren't worth it most of the time for me. That doesn't even take into account the constant changes in the name of "security" and the ever increasing "carry on" sizes (which drives me nuts!).
