I take full advantage too. You know their "Bacon, bacon, bacon" pizzas? Mine are more like Bacon, bacon, bacon, bacon, bacon, bacon, bacon, bacon, bacon, bacon, bacon!That can't hurt.
My son works at a local grocery store. He occasionally buys some food and brings it home. He gets mad when I eat it.
Seems he forgets the last 18 years we have been feeding him.
As soon as one of my kids got to the point of saying "Hey, that's mine!", I made it VERY clear that if its in this house or on this property, it belongs to me. I don't care who thinks they paid for it.
