It happened to my wife in the small airport at our former location. But, then, the first passenger on the standard line started shouting. In the gate area 20 minutes later, he was still loud telling my wife that she was wrong to have passed ahead of him. According to him, when my wife saw that there were passengers in a line, she should have put herself at the end of that line and not in the next line. The good news is that there was a First Class in that plane and my wife had a seat in that area. Imagine if she had had the bad luck of sitting next to that passenger: would have been a miserable 50 minutes flight.
