What strikes me is the text circled below the snip line:
"Visit undertaken by our Enforcement Division.
Please ask for identification."
This yank wonders if that indemnifies the glorious tvlicensing should you get attacked by an imposter.
Sadly, I am sure there are cretins that will take advantage of the notices to engage in predatory behavior.
Misery loves company, plenty of dickish corporate behavior in the States.
