The only thing as frustrating and time-consuming as standing in traffic for long periods is standing in checkout queues for long periods. So you can understand how someone who has been standing in a long line might go crazy if a free new line was opened and the people behind them took advantage of it. We’d lose our minds too.
Moments like these make us question if common courtesy even exists anymore. It’s obvious when someone has been waiting in a line for longer than you have, so why not do the decent thing and let them move to a new line instead?
