It is a lot more fun to Start speaking in German about them to your spouse and keep looking at them and laughing while speaking German.
Have any great dialog for this? In German. Or Gaelic.
I recently sat down next to a couple in a restaurant and heard them speaking German. I wasn’t intending to eavesdrop but they were right next to me. It was the most bizarre version I had ever heard. I had to eventually ask where they were from. They were from Koln and others must have questioned them in the past because they offered that they were intentionally speaking a mixture of various high and low dialects because they knew that otherwise too many in this area would understand too well. From what I could tell it sounded like a normal vacation related discussion, its odd that they felt the need to keep it so secret yet felt the need to talk in public where they knew there were ears.
