I came over all frothy in the park earlier when this guy walking 2 big lassie dogs - on leads- let one of them do a massive poo, 2 yards from his feet, on the grass where loads of kids play, then went to walk off.
I just got really mad and stopped and looked at him, then when he went to walk away said "Excuse me, please tell me you're not going to leave that there?"
He mumbled something about waiting for the other dog - so I stood and waited. He then mumbled that he didn't have any bags.
So I (v loudly) said "so you're just going to leave it for kids to step in? That's disgusting- you should be ashamed of yourself. "
I am 
There was football going on so people were looking, but I was just so grrrr about it. What an arse. I had DS with me (I was carrying him at the time) so didn't want to frighten him, but couldn't walk past and not say anything.
Pig!
