I think we all have funny stories about the language barrier. Here's two to begin:
This one is 50 years old. My mother's husband did not speak French. He addressed the hotel clerk in English, but was immediately asked if he spoke German as the clerk said he had no English. He did. They finished the conversation in German. Desending the stairs he overheard the same clerk tell a German he had no German. They concluded their conversation in English.
This year we relied on our moderately French speaking daughters to ask where to find things in Paris grocery stores. The clerks looked amused. I asked why and my eldest said it was because her French was so formal. What I'm saying the equivalent of, "Please kind sir, could you direct me to the ice cream?" The very next trip she asked a very tall black clerk where the eggs were. He bowed with a flourish and said in French that he would be pleased and honored to escort the exquisite Miss to the eggs. At the eggs he once again bowed and asked whether she'd prefer ten or four eggs. They both had fun.
About six years ago in the far reaches of London (Barking), I tried to find soy sauce without success. The clerks were Indian or Middle Eastern and those accents overlayed with British were difficult to my American ear and my American accent difficult for them. They did not know what this strange sauce was. Two trips later we found the soy sauce next to the catsup and mayonnaise but far, far from, the Worcester sauce or the Chinese noodles.
