I've seen gridlock before in New York City. It's when vehicles are choking at every intersection and literally no one can move. Until recently though, I had never seen gridlock in a grocery store. The weatherman had forecast a hugh snowstorm for our area which was supposed to begin during the night. Well I stopped by the store about 9:30 that night, and I ended up trying to find the end of the line for the cash register. They only had two lanes open and there was a line of carts all the way to the produce section all jammed together so no one could come in, go out, or go through. What brought this sudden urge to shop? Word of an approaching storm.
