I don't think I have ever noticed what a ticket inspector has scribbled on my ticket. It's not something I take much any interest in. I look at the person's face usually, and smile an acknowledgement.
If I had noticed that scribble, I'm not sure I'd have made the connection. I bet most people didn't notice. You just shove the ticket back in your pocket or bag and carry on looking out of the window, or go back to sleep, or read your book.
I like your comment, feetle. Straight to the point as usual. Zap
