Students at a Wellington school have been given an excellent lesson in the law of unintended consequences.
Healthy eating guidelines for tuck shops have had the opposite effect at Wellington High School - with pupils feasting on daily sausage sizzles and pies from the local dairy.
Let's hope it's a lesson that stays with them. It's still eluded most of their 'betters' in parliament.
(PS: Very pleasing too to see there's one dairy owner in the country that is doing well.)
