Standing in line is a complicated social situation with nuanced protocol and high penalties for faux pas. It's certainly a topic OOT has explored before, perhaps most recently in
"Buying a gift card - where do you wait in this line?", but I think we've barely scratched the surface. This is the thread to discuss all your queuing dilemmas, from choosing the fastest line, preference for single vs. multiple lines, line-like situations that aren't really lines (like waiting for the elevator), and so many more!
To start things off, did you know that here in New York, people say they are "standing on line" or "waiting on line" instead of "standing in line?" What a fun fact!
