German-English
Today the pharmacist switched to English after I had only said "Hallo." Is my accent that bad? Well, her English wasn't the best either, but it was cute at the end when she asked me "Do you have another wish?". Which is quite normal in German to mean "anything else?" ("noch ein Wunsch?") but in English is something you only really hear said by fairies or genies. Or maybe a 19th century butler.
But usually I like going to the pharmacy because I actually complete all my transactions with the salesgirls there in German and feel good about myself.
Update: A quick google search reveals I'm not alone with this
