Fun story about Camila Parker Bowles (sp?). I know a guy from Wales who was attending uni in Bath and was working in a cheese shop there. One day (after a heavy night in the pub the night before) in she walks and he attends her, and as he puts it: "Well, you know when you eat enough cheese it has a certain reaction." And he burped in her face.
He was fired.
To be fair, he did say "pardon me" and he had absolutely no idea who she was at the time.
