Just saw a funny commercial on TV about being courteous in a checkout line. Guy has an arm load of groceries but the guy behind has only one item. So, he lets him go in front rather than hold him up. As this is going on, announcer says that the next person checking out is the one millionth
customer and will be the winner of $50000. The guy with one item checks out, the band starts playing, the balloons come down and then he gets the check for $50000. The courteous gentleman just stands there stupified. So, remember that when you let someone go in front of you in a checkout line.
