When my dad was walking around London while wearing a London Fog coat (and working abroad in the petroleum industry for weeks or months at a time) tourists would ask him directions to places. He wouldn’t get on a high horse and tell them he was born on the East Coast of the US. He’d just give them a good answer as best he could.
I have often walked around London and other foreign towns in a fog myself. Unlike your dad, no matter how well dressed I was, people always seemed to sense that I was lost and hastened to help me out!
