We came across this machine in a mall. It's the first time in my life to witness such a vending machine. Cool.
Accept only cash and coupon. Kind of limited options, given there exist so many kinds of third party payment methods... $70 NTD /e.a. is not expensive really...
So we bought one. See the sharp teeth processing (to punch a hole for the straw)?
viola! a fresh coconut with a hole punched, ready for quenching your thirst. Nice!
Proof of Freshness - that's what this machine sells. lol
