So I checked out today from a Hilton hotel in New Delhi. I told the checkout person, I only wanted to pay in India Rupee. I used my Sams chip and pin card. The card never asked for my pin. I signed it.
The point here however is about DCC. He said if I use this terminal when it shows the cash amount, a green will allow the USD transaction. The yellow leads to USD transaction. He also showed me a smaller POS, which he said only spits out USD, no choice. sorry, I did not take down the name of the device.
