Polite shuffle

When you and another person come up to a path (like an intersection, a doorway, or a narrow hallway) where only one person can go, and you politely tell them to “go ahead” and they say “no, no, you go ahead” and then you both wait, and then go at the same time thinking that the other person will not concede, and you repeat this at least one more time.

Two drivers pull up to opposite sides of a 4-way stop at the same time. One is turning left, the other is going straight. The person going straight signals to left turn person to “go ahead”, while at the same time, the person turning left signals to the person going straight to “go ahead”. They signal back and forth and then wait, and eventually concede at the same time. They laugh and repeat the polite shuffle at least once more.
