If you can't direct me to a manager, someone else can. You are the only employer in the establishment?!
More fool you if you think a simple 'No' will dissuade me from making a complaint if it is called for.
I know that many people take advantage of Apple's return policy for whatever the reasons...doesn't excuse the fact that it is not right. It's not on the same level is stealing or attacking someone...but I never said it was.
Nowhere does Apple say "purchase-use for limited amount of time-return item for full refund" is an approved method of obtaining a loaner device.
Nice try, but no dice.
