Maybe it was a real-life example of the Chinese Restaurant episode of Seinfeld:
GEORGE: Excuse me, I was waiting here.
WOMAN AT PHONE: Where? I didn't see you.
GEORGE: I've been standing here for the last ten minutes!
WOMAN: Well I won't be long.
GEORGE: That's not the point. The point is I was here first.
WOMAN: Well if you were here first, you'd be holding the phone.
Maybe the guy was too busy blabbing on his phone in the back that the lady didn't think he was in line. But then again, she ended up spewing tons of expletives, spit at the manager, and her friend beat the living crap out of the guy.
What a wonderful world we live in...
