I don't agree with children in pubs or pub gardens. Firstly because I don't want other peoples kid running around me while their parents glance over as if to say 'aren't they cute?'. No they are not. You only think so because you are their parent. If I wanted children around me I would have my own to annoy me. Secondly, what about the kids? Children should not be around loud, swearing, smoking, drunk people (especially if those people are their parents) and drunk people should not have to worry about smoking, being loud, drunk and sweary in what is ultimately an adult environment.
