What do you call a line of men waiting to get their hair cut?

I like this one verbally because you have to awkwardly explain it's the queue line not Q part of the joke when they look at you like oh barber instead of bar b, wow. you have to be like NO NO IT'S A QUE U E LIKE A LINE SO IT'S FUNNY.

Ok I may be a bit

I thought it was "hair line". Derp
