Someone has just said to me 
Woman exercising 3 dogs with her friend and two children in said playground. Dogs running loose everywhere. Playground fenced off with gate and very clear signs that say 'dogs not allowed in playground'.
Couldn't believe it and felt I had to say something because there have been numerous occasions of dog waste in bags left around the playground. I'll be honest I was annoyed. But I was calm and polite and said 'you do realise dogs shouldn't be in the playground' which she got flustered and said she'd already removed them when she saw us coming (she had literally just scampered through the gate) I said that wasn't really the point, that dogs create mess and there's a whole field next door for them to play in! And so on. She claimed that we just had a difference of opinion.
Fwiw I love dogs and have two. So not a dog basher at all.
Was I being the fun police or was she a self entitled twat
