Sorry, a stranger.It’s not clear from the story if this was a travelling companion or a stranger asked for directions.
A complete and utter stranger.
Indeed.If the first I’d have told them you’ll make your own way and see who gets there first.
In future, I may well do this.If the second I’d have left them to their own devices.
After asking a rhetorical question (as to whether they believed Google maps, or the evidence of their eyes) I did tell them to suit themselves and withdrew from the exchange.
