If I encountered such a machine, I would take a photo of the merchant copy of the rupee slip alone, and chargeback based on that. I will deny seeing the stand alone DCC selection slip, claim it was printed ex-post and therefore ineffective for evidencing any purported approval of DCC on my part - parol evidence rule used against the merchant for once.
