"Three years ago, I was catching a plane at Boston’s Logan airport and went to buy some magazines for the flight. As I approached the cash register, a woman coming from another direction got there just behind me — I thought. But when I put my money down to pay, the woman said in a very loud voice: “Excuse me! I was here first!” And then she fixed me with a piercing stare that said: “I know who you are.” I said I was very sorry, but I was clearly there first."
