This "study" is totally bogus. Another English-centric piece of nonsense. First of all, the respondents were mostly from people who probably only speak English and don't speak a second language (60% from Ireland & UK plus Australia & USA). If you have these English-only speaking tourists who visit "foreign" countries and expect those people to speak English, then the French, Russians, and Germans have every right to be "rude" to them. Ever try speaking French to a New York City subway attendant? Or, how about speaking German to order dinner in Manhattan?

If you want to visit a foreign country, at least attempt to learn a few phrases in the their language. It's not hard.
