The same thing that literally EVERY single host/hostess at every restaurant will say to you as they show you to your seat. Pay attention to it. It really is incredible.
A common method that Massachusetts drivers use when taking a right or left onto a road where they do not have the right of way. A driver will turn out and cut other people off. Instead of turning onto the main road and speeding up, they will pull out, realize they are cutting you off and then come to a complete stop while turning onto the main road, until the driver(s) they are cutting off stop to wave them on. It's one of the most infuriating and dangerous parts of driving in Massachusetts.
