I see in the local chip wrapper that dog walkers are being used fairly target by privately employed council wardens.
I had one approach me a while back whike I was out with Bruce and he demanded that I prove that I had poo bags with me. I did, but that's not the point - I was doing nothing wrong andnhe wasn't the police, merely a private citizen with no powers. So I said to Bruce, "come on Ben", and slowly walked away while completely ignoring the nodder. After a few hundred yards he gave up following me and went to look for easier pickings.
Do not engage with private citizen contractors employed thus by councils - they have no powers and if they dont know who you are there is nothing whatsoever they can do. Not a sausage. Just blank them as if they weren't there.
