I snapped this at a friendly lunch place on the Dutch island of Ameland. Although Schnitzel Stroganoff sounds odd enough in its own right, the use of ‘plate’s’, which is ‘plate’ in English with Dutch plural (‘s), makes it Dunglish.
You’d think it’s for the English-speaking tourists, right? Nope! Ameland is a Frisian island, so after Dutch – or even before – the locals speak Frisian. Then there’s all the Germans tourists to think about. That could easily explain the schnitzel.
