Was stopped the other Monday near home 5 minutes outside window hours. Fair enough. However, I could only produce my UK driving license, not my local one.
I was waiting for the time honoured phrase, "...but I can help you" however, all I got was a good telling off and a warning, "Next time!"
I can live happily with that. A TE who takes the time to advise a stupid foreigner (we're not required to carry a license in the UK) rather than immediately trying to hit on you for money. License is now always in my wallet!
