Ninja Inflation

Hidden inflation, such as when a restauant serves smaller portions, instead of raising its prices. Since the reamains the same, it's not easily seen by the untrained eye; it's hidden like a Ninja. But the inflation is surely there!

Friend A: "Heyyyy, wait a minute...didn't this dinner entre used to always come with 3 pork chops? I've only been getting 2 now for a while...but at the same price as before..."

Friend B: "Yeah, man...that is called NINJA INFLATION!!!"
