Ness, had the exact thing happen in California last summer. Staying at a motel waiting to get ready for my niece's wedding and spoke with a couple at the pool. They had a foreign dialect with their English and I'm sure my "Ozarks" English threw them off. They were from Switzerland, where my paternal great grandparents came from and the lady had lived in the same town. When I pronounced my last name, she said "No, it's pronounced this way". 64 years old and pronounced it wrong all these years.
