Well, I haven't used them in a riot but have enjoyed the bathrooms and Wi-Fi. I always make a purchase. I some places they're also the only place you can get early-AM coffee outside of the very expensive hotel restaurant. I have fond memories of morning runs in Budapest and St. Petersburg.

Before I visited our offices in India one of my colleagues told me how great the locals were about ordering in every day for lunch: Pizza Hut, KFC, McDonald's (the non-veg crowd favored Chicken McTikkas). they never did that for me. I suspect that it was because I raved about the local food from Day One, including the stuff they served in the cafeteria!
