Adrienne and Vincent Clarke, originally from Sligo and Louth, run Eirelux pub in the centre of Luxembourg city.
Whilst on holiday in Lanzarote, Adrienne got an unexpected call.
"I was relaxing on holiday and the phone rings with a very official voice," said Ms Clarke.
"I thought, oh, this has to be a scam, this is not real. This guy is really, really good."
