Would You Take Advantage Of A 'Double Your Money' Cash Machine?

What would you do if a faulty ATM (on a camera linked to every transaction - they know where you live!) spontaneously give £200 in your favour every time you ask for £100?

(1.) Tough luck! Take the effen 'profit' and run.
(2.) Grin and take advantage with several cards.
(3.) Come back every day and take more free money.
(4.) Happily spread the word to friends & family.
(5.) The bank camera is against my right to privacy.
(6.) Return the money and charge the bank phone hold time fee.
(7.) It’s not mine! I'd own-up and return the money.
(8.) Report it to the police.

What would you do?
