Yes, I was an American hockey mom for years, crossing back and forth to Canada many times. It’s luck of the draw. Some guards really, really take their job seriously, too seriously. We learned not to talk or offer information that wasn’t asked, never joke. We learned the rules. We also learned to make it very obvious our son was a hockey player - sticks and gear in sight!
When I went to EU I was so worried I would have this issue but nobody asked beyond my answer of traveling for “holiday” thank goodness. I had addresses and names of the HO and warned them the border patrol might call to confirm I was staying with them. “Staying with locals and in airbnbs.”
