I had one guy at a gas station in New York say to me, “Hey, you look like Hugh Grant. No offense.”
— Hugh Grant

Our reading
An editorial interpretation.
The stranger compares the speaker to Hugh Grant, then adds 'No offense,' as though the resemblance might be insulting. For Grant to recount the remark makes the joke self-directed. Recognition and an unintended put-down arrive together, making the polite qualification the comic surprise.
