I’m Singaporean and I have absolutely no idea why there is abalone in the vending machine. But it is a ready to eat version so I guess it’s just the vendor giving the buyer some variety? Haha. Weird but not totally weird as well since giving abalone as a gift is considered an expensive gift here.
That's Gardens by the Bay, not the Singapore Botanical Gardens. The later is a whole different place.. you should visit it, if you have the time. Nice vids!
