Now take a look at the picture above. Notice that two people hang back leaving a large space between themselves and the people at the counter. That's OK, they're probably not ready to talk to the counter yet. Nothing wrong with that, that's fine, but I've been in fast food restaurants where the line starts this far back and the people in line get indignant if you walk up to the counter and try to order. What's with that?
My guess is that that men who don't know how to form a proper line are the same men who leave paper hand towels in urinals. You know who you are!
