I am sure all of you out there have been in the two lanes of traffic must merge into one situation. When traffic is moving at a crawl, the zipper tactic is the appropriate one if you ask me. One person from lane A then a person from lane B and back to a person from lane A again. Why is it when one person doesn't follow this pattern seven people behind them continue the trend letting eight people from lane A go before another person from lane B gets to.
It is very rude to think that other people's time is less important and they should wait longer. I think we should sent those people back to Kindergarten, where they can learn about sharing again because obviously the first set of lessons didn't sink in.
