Yes, the french aren't our only problem

At the supermarket counter, yesterday afternoon. The players: Myself, confused blonde girl in front of me.

Me: Scusi, Lei è in fila?
Her: ... (blank stare)
Me: Are you in this queue?
Her: I...I don't know...
Me: Are you from the United States?
Her: Yes.
Me: Oh, i'm so, so sorry.

So i passed her by and went on to pay.
