Why?

Is it a littering problem? I know some places ban own food because of that. Or because people bring in glass bottles and use them as weapons.

I'm sure there are reasons other than a profit margin. Although that's our first thought because that's where it hits us. Then I picture just the local park/common, or the field outside DS's nursery, with bins on it, after a sunny weekend. It's hideously littered. I can see a reason for the village council to ban picnics. Not that it would be popular.

Having said that, I would still be taking my own food. But I also bin my litter or take it home with me. I can't afford what my son eats if I don't take my own.
