Dadtax
A portion of any item received by any household member that the Dad is entitled to. Most often applied to food and drink items. Applies to items given to or purchased by any household member as a contribution for all the wonderful things that a Dad does for the household without recognition or reward. The tax is applied entirely at the descretion of the Dad and can be used at home, in the car, at the shops, at friends houses, or anywhere else in the known and unknown galaxy.
