It’s so easy to clear up your dog’s mess

Dear Sir, — We are very lucky that we are allowed to walk our dogs on lead around the pitches next to Congleton Leisure Centre. If people walking dogs do not pick up their mess, soon we shall not be allowed. This morning I counted five loads, three fresh, parallel with the side of the leisure centre, just where people stand to watch the rugby. 
It is so easy to clear up after your dog — please do so from now on or accept the consequences. — Yours faithfully,
