I was waiting in line at a train station last week to fix a mistake for a booking. It was a long line in front of multiple service desks, but only three windows were open and most customers had a complicated issue. So I had been waiting in line for a good 45 minutes at that point. A fourth window opened up suddenly, so the young couple at the front of the queue line started to move towards it. Suddenly an elderly gentleman appeared out of nowhere and made a beeline for the open window. The couple got his attention and explained to him that there was a long queue and he would have to wait like everyone else. He ignored them and tried to talk with the cashier. Fortunately the cashier was having none of it, and told him to go to the back of the line. He argued with the cashier for a good two minutes and then left in a huff.
About three minutes later he was back, and went to stand behind another customer at the window so that he would be served the moment they were finished. This time members of the queue line protested loudly. Once again, he started to argue that he was in a hurry and didn't have time to wait, but in the face of about forty irritated people, he left, for good this time.
