A poster referred to Americans and full English breakfasts.
Anyone who's ever had a buffet breakfast in the US couldn't fail to notice the weird mixture of food items they put on the same plate. More than once people I've seen people piling on stuff like egg, bacon and sausage together with strawberries, kiwi fruit and melon, sometimes with a blob of whipped cream on top.
Having breakfast in a London hotel years ago I saw a woman order kippers. When they were brought to her the look on her face showed she didn't have a clue what they were and weren't what she was expecting. After a little hesitation she began spreading marmalade over them and tucked in.
