I believe that most of us have to deal with the odd idiot here and there. I also believe that most of us are paid sufficiently well enough to remain tolerant, patient and polite with those odd idiots. Security staff process thousands of customers per shift (far more than bank staff). That will equate to a significantly larger proportion of idiots. They are paid peanuts. If you have an issue with the number of available security channels, take that up with the airport authorities. It's certainly not the security personnel's fault if they're short-staffed. I would just love some of you guys to have a go at doing the job for a month and see just how long you could keep your cool.
