Because the history of 할로윈 and the traditions it branched off of began before that saying. Also when one says "trick 또는 treat?" it's really a threat, if 당신 look at the history, it implies that if the resident of the 집 doesn't give whomever a "treat" he 또는 she will damage the property, so one isn't being given 캔디 의해 a stranger but taking it.
It's supposed to be "Never take 캔디 from strangers except for Halloween." Parents say that so they send their kids away for the night because they're going to take a nap.
