I have a big-ish pushchair, which is my fault (the things no-one ever tells you when expecting your PFB etc etc etc). It is sometimes very hard to negotiate pavements strewn with turds and I am sick to farking death of gagging and cleaning out the treads on the wheels.
Have been thinking for ages that the next person I see letting their dog crp will be asked to pick it up, and if they don't I will follow them home and smear the shte on their front door.
But I never see them - tis obviously the gits who walk dogs early or late and count on not being spotted.
