TerryKitten, we actually tried it once just to see if it worked... we had abouyt 15 people in our line within 5 minutes. My 2 friends and I stood in a row and didn't talk to each other, so it was like we were strangers. Ater a while, I just said I was tired of waiting and would come back later. They staggered after me. I have no idea how long the rest waited.
There's even a play about this called Line. It's short and very funny. Each person thinks they are in line for something diff.
