I regularly - say twice a month - see dogs in the dog-free area. On most occasions, I speak to the dog owners and politely suggest that they must have missed seeing the 'No Dogs' signs.
Reactions range from contrite to aggressive - with the unpleasant and aggressive far outnumbering the reasonable ones.
Occasionally, I walk by without saying anything, when I just don't feel like being abused or even threatened.
How do others handle this - or am I the only one to get involved?
