Broadly I think Sainsbury's have acted absolutely correctly. The reply on here from the manager was very good. This really isn't their issue. I think they should speak to the school and any other schools whose children may also get involved in this sort of activity. But without school supervision or even engagement, I think a total ban is the only solution - at least for a period ie a term or 3 months.

I can't honestly think why most school children would want or need to go to Sainsbury's. Lunch is available at school or can be brought from home or bought in other shops - ditto breakfast. Shopping on way home for Mum? Well go home, get changed and go back or go to another shop.

Sainsbury's already have more than adequate security and plenty of staff around. And they are a commercial business not a charity or after school club. I think we should all butt out and leave them to run their business as they see fit, as long as they do it legally and safely.
