From the comments here:
I have just sat through a council meeting where it has been seriously suggested that planning should stop fast food outlets within 400m of schools because it encourages obesity. It just encourages me that I am right to leave the council at the end of my term
Of course some other places have already passed such nonsense:
St Helens council has set a 400m fast food “exclusion zone” around schools and sixth-form colleges.The step was taken in a bid to reduce childhood obesity.
Personal responsiblity - no way, those kids are drawn to the chippie as if by magnetic force!
