moondog, jeffjaguar: I tried

In Harrods, I spoke to both a supervisor and a Harrods Black Card concierge. Both confirmed no HKD reversal http://www.flyertalk.com/forum/u-k-i...-currency.html

In GL, I even thucked youed the GL customer service rep to his face in front of my dotted line manager http://www.flyertalk.com/forum/franc...lafayette.html

All I got were apologies (Harrods) and advice to see my issuer bank (GL) (for which I thucked the rep).

Perhaps you need to see one of those POS terminals to believe it - it's one of those where the register spits out the sales invoice and card slip in the same thermal slip. There is no stand-alone card terminal (as commonly seen in HK/Macau/China).


Two other indicators that these terminals can run a refund only:

- at my first DCC at Harrods, I asked the junior cashier to void the whole slip and charge it again. She confirmed she can only refund the whole slip, then with my permission proceeded to so in GBP and recharge the whole purchase in GBP. All I achieved was to incur the GBP MC spread.

- on a subsequent purchase (no DCC) I bought seven items and very shortly returned one item. Instead of voiding the charge and replacing the invoice (as shops would in Hong Kong) I was given an additional slip for the refund of one item (and the card refund printed underneath).
