Glaikit gillieperous dog walkers

Lots of people walk their dogs on the local nature reserve. The great majority clean up after their pets but a selfish minority don't and the reserve staff are trying to educate them by drawing attention to Rover's ordure.

I don't know who annoy me the most, the anti-social dog walkers who don't bother to clean up at all, or the glaikit gillieperous ones who do carefully pick up the mess and put it in a plastic bag only to leave it lying on the path or verge!
