Good for you, you have not even begun to think about yourself, like most human beings, thinking of others first. Of course you let the feeble old lady behind you in line have the next turn at the ticket counter, of course you did not let the other feeble old lady behind the feeble lady's friend behind you have yet again the next turn at the ticket counter. Upon denying your right of "the next person in line, please," the feeble lady's friend took her Mary Poppins carpet bag, somehow hoisted it above her head, and let it "accidentally fall" onto your hand holding that steaming hot caramel macchiato. Yes, the insides of your thumb and index fingers would now forever be a slightly different shade, and yes, your duty free right foot Sperry shoe would now forever be, no longer. This is only your first encounter with your fellow passengers. Jolly.
Punch Line…. If anything in your whole airport experience would be right, it would be your injured hand and destroyed shoe.
