>That somewow reminds me of a friend who confused the waitress at a restaurant, asking for an orange-taste Coca Cola. Pressumably he wanted Fanta.

Many years ago, a friend was visiting from New York, and we went to a diner type restaurant. He asked for a chocolate coke. The waitress looked at him like he was from another planet. She said, "Chocolate coke? What's a chocolate coke?". He had to explain that it was just like a cherry coke but with chocolate syrup instead of cherry syrup. She brought it, but she gave him a look that said she still thought he was crazy. For the record, I agreed with her.
