It's like the one person did it once and since then everyone has followed

How does one person form a queue?

But, yes, everyone else following is definitely how it would happen.

That's something I've also never liked about bars that I tend to not even mention when I say why I hate going to bars.

It's stupid how they choose to serve you. Having a line makes sense. Doing whatever a typical restaurant does makes sense. Doing whatever bars typically do is utterly ridiculous. Fucking serve me and stop flirting with the hot blonde.

Meh... I dunno. I won't miss a loud fat obnoxious bloke having pushed me to the side at the bar and shouted their order at the bar person whilst waving a twenty quid note in their face cutting in front of me. If that's what we're yearning to go back for the I won't miss it.

Maybe the yoofs have more of a sense of fairness and have started to queue?

I don’t see the problem here.

Does it decrease profits when people are served in an orderly fashion?

Edit - genuinely, I don’t understand. Why the downvote?
