My favourite pushy people story is actually from an airplane. We were on a flight from Madrid to Newark. Upon landing, everyone stood up in the aisle (as we all do), and waited for the door to open to the jetway. A woman behind us started staying "excuse me! excuse me!" and pushing her way through. She got to my husband, who was behind me, and said, "excuse me, I have a connecting flight!". He turned to her and said, "and we don't?". That shut her up and she meekly stayed in the back.
I was a landed immigrant at the time and was taken to immigration to have my documents checked, and she was there too --- but they didn't release her for whatever reason. Guess she missed her connecting flight. Maybe it was Karma?
