You approached me on Monday while I was lying on the grass, minding my own business, and told me that the area of the park I was in was exclusively for dog owners. When I questioned the sanity of such a statement you told me that you worked for the council and so you were correct.
*IF* you genuinely do work for the council (you look the type) as you claimed then can I just say that your inability to comprehend the difference between "dogs may only" and "only dogs may" will probably be the reason why you can't get a proper job in the private sector. I for one would not employ someone so clearly lacking basic comprehension skills.
The thing that frustrates me the most is the attitude of desire for segregation. I know that dogs are banned from the kiddies playpark area (and have been since the 1970s). Part of the reason for that is the irresponsible attitude of some dog owners who, even in these enlightened times, still refuse to clear up after their animal if it does a shit. Part of the reason is because of the fear that some people have that every dog is just biding its time and will eventually turn into a savage killer, most likely when their darling child is around. Personally I think that dogs should be allowed to go to all parts of the park provided that their owners are going to take full responsibility for their actions. The polar opposite of your solution.
Maybe you could start a campaign to teach your fellow mutt-lovers to be more responsible? That way we could all work together and reduce the amount of nannying fussbuckets that work for local councils who try to bring in bans for all manner of petty things.
