Recently, on a flight from Orly Airport, I stopped at MacDonalds for a quick burger. Whilst sitting down enjoying my chilli-burger, I saw a couple of mice wandering around the place fairly boldly without fear of human beings. When I pointed this out to the manager of MacDonalds he told me smilingly "they are all over the airport, Sir, but my kitchen is very clean although you may find one or two in your burger". Has anyone seen this at any other airport or local eating establishment?
