Rationing Toilet Paper

 

I spotted a news item to the effect that some supermarkets are restricting customers to at most three packets of toilet paper. I wonder how they measure the quantity. Toilet paper seems to be sold in packs  ranging in size from two rolls to at least 16. It would be strange to condemn someone buying four packets of two rolls as greedier than someone else who buys one packet of 16.

 Buying four small packets would indeed be odd. but odd cases are often good tests of rules.
