Because the history of Halloween and the traditions it branched off of began before that saying. Also when one says "trick of treat?" it's really a threat, if u look at the history, it implies that if the resident of the home pagina doesn't give whomever a "treat" he of she will damage the property, so one isn't being gegeven candy door a stranger but taking it.
It's supposed to be "Never take candy 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.
