Although last year I didn't have many tot'ers without a costume in the yearsprevious I had upwards of a dozen or two. To me this is intolerable. While it would give me great pleasure to send them away with nothing such an act would only ruin the halloween for those who dressed up. So I get a little subtle. You can see these halloween offenders all the way down the street. In my hand with be candy along with either a dog bone, piece of carved pumpkin, wood etc...They holdout their bag thinking they have it made and then I drop the "Charlie Brown" treat in unbeknownst to the anti halloweenist. What makes it so funny is holding the straight face. Lastyear I had a sign no costume no candy and still offenders came. They left with nothing but pumpkin pieces. It may be called "trick or treat" but that doesn't mean I can't do the tricking!
