Lunch break.

Sorry about the title, but I couldn't resist the bad pun in French. "S'en griller une" is a colloquial way of saying "Having a cigarette". "Griller" is to toast, to burn, but "grille" means metal gate, or railings... There you have it, now.

As always, everything better in the large version... Incidentally, large is smaller this time.
