Assuming you checked in a room with a KFC at a rate of $200/60/1. And assuming you finished EVERYTHING in 30 minutes. DO YOU THEN:

(1) wash up and leave, given that the $200 objective has been met; or

(2) lie there and watch TV, waste time until the full hour is up, then leave the place to feel WU HUA, thinking that you have fully amortise the $200 over 60 minutes?
