Smoking ban

I once sat beside a very well off Mexican family in a very well ventilated restaurant on the beach at lunch time. There was a two kids, a husband and wife. I had just been served my lunch and the man fired up a big cigar. I turned around to him and asked him to put it out. He waved me off, laughed and said that this was his country and he could do what he wanted. I said "not around me, you can't". I went and found the head waiter and he very respectfully handled the situation. The man and his family got up and left with the cigar still stuck in his mouth.
