Bronn (to Tyrion): Have you ever been in a city under siege? Maybe this part’s not in your books. See, it’s not the fighting that kills most people. It’s the starving. Food’s worth more than gold. Noble ladies sell their diamonds for a sack of potatoes. Things get bad enough, the poor start eating each other. The thieves, they love a siege. Soon as the gates are sealed, they steal all the food. By the time it’s all over, they’re the richest men in town.
From Game of Thrones – Season 2 Episode 8: ‘The Prince of Winterfell’ (2×08)
