Oh I think 1 in 10 at least has to have some kind of clue.

Just to share a story, I was dating a guy when I first moved to Doha for about 3 months. One day he takes me out to dinner and says to me "Um, my girlfriend is coming to visit next week, so is it ok if we pick this thing up after she leaves?"

My jaw hit the table and I just got up and left and never spoke to him again.
