What to do ??

Trick or Treat: Lots of kids dressed in Niner gear arriving. I've decided to take what my wife calls a "horrific example of bad behavior". I open the door and refuse to give candy to the little ones wearing SF stuff-usually helmets. The others leave with their candy leaving the little Niners crying before me. Do I give in? No-I laugh and laugh and laugh at the little buggers. When the dad's approach I shut the door.

Was I "below average" ?
