Never again am I going to a country where I can't speak the language. German is so completely opposite to any language I have ever studied that I literally had no hope. Every time I tried to order some currywurst mit brot I would blindly flail around in pseudo-German (dankers) before shamefully resorting to English, which of course they could all speak. I felt like a complete ignorant tourist.
On the odd occasion where the Germans weren't more apt at English than I am, communication fail ensued. Replying 'no thanks' to 'where are you from?' for example.
