That comment was based on a experience I had recently at the airport, I was happily waiting in line, just one guy in front of me when a old Japanese guy working for the airport come to tap me on the shoulder "Go, go" indicating a empty line, I could not care less to wait but nevertheless complied just so he would shut up, just start to line up there and on the line to my right there was a gaijin couple, the guy came to me and told something like "You just took my place ...", I just told him I was told to line up her by the old guy and to take it easy. He went back to line up with his gaijin girlfriend and it took less time for the two of them to pass the control, maybe because I am resident I guess there were just tourists, while the officer was checking my documents the gaijin guy come on the other side boasting saying things like "Hey, you stole my place but I am here before you", just ignore him and hope that he would be gone when I get on the other side because he seemed to be real nutcase to me, although his appearance look quite normal. I have the impression people like that are becoming the norm in the Western therefore my comment.
