The machine's rate: 1 EUR = 0.9000 GBP, against 0.8500 mid-market.

What DCC is

Dynamic currency conversion is when a card machine, cash point or checkout abroad offers to charge you in your home currency instead of the local one. If you accept, the conversion happens at the merchant provider's rate rather than your card issuer's rate, and that rate usually includes a margin on top of the mid-market rate.

Which option to pick

When asked, picking the local currency usually works out cheaper. Check your card's own foreign transaction fee before you travel, since some cards add one, and compare the amount you're offered with the mid-market rate if you're unsure.
