Because the history of हैलोवीन and the traditions it branched off of began before that saying. Also when one says "trick या treat?" it's really a threat, if आप look at the history, it implies that if the resident of the घर doesn't give whomever a "treat" he या she will damage the property, so one isn't being दिया कैन्डी द्वारा a stranger but taking it.
It's supposed to be "Never take कैन्डी 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.
