It's difficult to know what to do about the (hopefully) minority of rowdy, disruptive school children in local shops and supermarkets. When their behaviour ends up causing someone an injury, then obviously something has to be done.
What are the schools themselves doing about it?
I think at the moment, the "two only at any one time" is the best and fairest way of dealing with the problem as it doesn't punish those kids who are innocent. It may take a bit longer for them to get served but if they are genuinely there to get something to eat, they should be able to nip in and out fairly quickly. Perhaps a dedicated check-out till at the appropriate time might be a good idea, so they don't have to queue behind those with full trolleys?
We have the same problem in our small town - but often the kids are just simply unaware that they're crowding the pavement in groups - they're not really intent on causing trouble and are quite apologetic when they realise they're causing a problem.
It's the same-old-same old. A minority of unruly kids acting like little oiks because their parents simply can't be bothered to teach them to behave. When you see some of the parents dropping off their younger offspring still dressed in their pyjamas, it does make you wonder how much they care about such things as discipline. I might get shot down in flames for even mentioning that, I know, because so many people believe that it doesn't matter if they are still in their nightclothes - and maybe I'm wrong, and maybe it doesn't matter, but I don't think it sets a good example to children.
I don't mind kids being noisy or being a tad lacking in awareness - they're full of life, energy, and natural enthusiasm. One such, who was shouting and waving his arms around in all directions the other day offered to carry my heavy shopping bags back to the car. It's just a minority of little louts-in-the-making who are intent on being a PITA.
