Queuing

I am one of these people who ALWAYS take the wrong queue at a supermarket or wherever I have to stand in line. And if I change the line in the middle of everything, the cashier in my new queue most certainly gets heart attack just after it is too late to change back.

For my comfort, I am not alone with this; I have found out that many people have it like me. So if there is maybe half of the population being unlucky like me with supermarket lines, is the other half very lucky then? Is someone right now writing in her blog "God, how lucky I am always choosing the right queue at the supermarket" ?
