It's great that you had such a good experience. I've never been to Ireland, so I can't speak for DCC there. I think many of us have just being overly sensitive to the subject where there have been cashiers who have actively deceived us or gone against our wishes and selected the card's native currency rather than local currency. In some parts of the world, the terminals are locked down or provide no option; DCC is forced. Other places you'll get employees who you suspect know what they're doing, but then they attempted to feign ignorance or say the USD/xxx amount is only for your information.

Fortunately in the UK or Ireland there's not a language barrier, and it's great that you were presented a choice each and every time. (I assume this was unprompted, or were you asking to charge euros every time at the places with DCC?) That's all we're really asking for. I think my fear about Ireland was I had read reports that Burger King forced DCC without a way to disable it, so I assumed that the payment terminals at other establishments might be configured the same way.

I think DCC for whatever reason is far less of a problem in the UK. The only place where I've been hit with it has been at a Marriott hotel (before I knew what DCC was). Harrods also has it, but it's easily avoidable as long as you tell the cashier to charge pound sterling upfront.

I guess I have nothing to fear when I make it to Ireland, and above all else I am truly grateful that there is no DCC at Nando's. There wasn't DCC at Nando's in the UK either (November 2011) nor in Australia (June 2014).

Congratulations on a DCC-free trip. ^
