What a difference a hyphen can make.
Today's Dominion Post contains an advertisement for the annual Carols by Candelight concert hosted by Nick Tansley at Wellington's Waitangi Park.
It includes the words "Alcohol Free". If that were the case, every freeloading drunk in the lower half of the North Island would be there.
But put a hyphen between those two words and it conveys quite a different meaning - the one I'm sure the organisers intended.
