Eem excuse me but I was here before you... AIUB. to have said this

[warmandwooly]

To the couple in the coffee queue who saw me at the other end of the barrier and didn't ask was I waiting or acknowledging I might have been there cefore them to the barrister

There is no need to get a barrister involved! It was only a queue!

No you wnbu! It's Barista...

Were you at the correct end? Or were you waiting at a far flung end of rope when no-one was there... If neither of these apply then YANBU

YA probably NBU but it's best to let the little things go. Did you get your coffee eventually?

Were you waiting at the wrong end? If you are British you need to know how to queue correctly

I was behind someone so that to me is where the queue was.its gone. Its done but manners cost nothing!

Funny, I read this post, went back on google and found this website iwasherebeforeyou.com haha. Coincidence ???

Were you waiting though or had you been served? Agree with @Byeckerslike, no need to go to court about it
