I didn't realise it wasn't 'legislation' - at Coles the 18+ rule has been in placed for at least a year (I started there beginning of last June). We have to be 18yrs or older and trained (watch a video, do a quiz sheet) before we can serve cigarettes. I've been there a year, get a lot of night works, and they haven't trained me yet (supervisors get annoyed), but I have served them before with permission from Duty Manager as I was the only one that could.
