She's All That And A Bag Of Chips

I hereby propose a new sharing rule that applies to all sweets and savories that are packaged in a bag.  If you offer some to someone and it takes them longer than three seconds to withdraw their hand, you crush everything in the bag.   This rule does not apply to gummy candies since any attempt to crush them would prove futile.
