I have been known to make people queue ;)
its a british thing can't help it!

really annoys me...

acutually reminds me of story.
I was queueing and a gentleman pushes in front (not a Q)
I coughed loudly
and this Qatari boy in perfect english said... she wants to know why she is invisible and not being served.

It was so funny! i love it when people diffuse a situation to laughter...
