Here's the link to the article on Yahoo News. But I will give you a little taste to wet your appetite.
This month marks the beginning of student-travel season in Europe, which means that — at any given moment — continental McDonald's restaurants will be filled with scores of American undergraduates. Quiz these young travelers, and they'll give you a wide range of reasons for seeking out McDonald's — the clean restrooms, the air conditioning, the fact that it's the only place open during festivals or siesta. A few oddballs will even claim they are there for the food.
European onlookers will tell you (with a slight sneer) that these peripatetic Yanks are simply seeking the dull, familiar comforts American culture. And this explanation might be devastatingly conclusive were it not for the fact that European McDonald's also happen to be crammed this time of year with travelers from Japan, Brazil, Israel, New Zealand, Argentina, Korea, Canada, India, Taiwan, Australia, Mexico, South Africa, and — yes — neighboring European countries.
