This happened to me last year. Not so much sucky as strange. I worked last summer for a company that did day tours on Prince William Sound in Alaska. We got a lot of people from all over, Australia, Germany, Canada, Prague, a couple South Africans, just all over.
I was in the galley and this short, round, middle-aged man came up.
Him: Un café? *points at the coffee* Sorry, sorry, I French, don' speak English.
Me: Coffee. Sure. *fills the cup*
Him: Sorry, don' speak English. I French.
Me: *smiles, hands him the coffee*
Me: Pas un probléme.
Him: *agitated* Sorry! No English! I speak French! *walks away, muttering*
