so my godparents and their kids were in Germany, in their summer vacation and they went to a restaurant. they knew German a bit but obviously not enough

and wanted to look cool and special so they ordered in German. one of the kids, the boy (he must've been 17 at the time) asked for a hot dog with mustard and he was like "mit seife" instead of "mit senf" and the man who took the order looked rather puzzled at them and smiled. they found out later that they had asked for hot dog with soap
