This propaganda video from Leith has it all and says it all!
It introduces the concept of happy, helpful enforcement wardens. They dance along the path, they look kindly at squirrels, they give out rewards!
It has jolly music, it has a dog barking in time with the music, it has a happy, cheerful dog owner.
It has a reward from A1 Pets, although the one comment on that page does give cause for concern but I stress I have no personal knowledge of the shop.
Watching this video made me want to go to the park and clear up some mess just to get a free voucher! I can hear you now, humming along to the catchy tune!
