I have a coffee at the Killarney at least three times a week.I have never been ripped off.I have always been delighted with the coffee quality as well as the service .I can only suggest that perhaps the “mumbler” was a part timer or a new staff member which could perhaps be a heads up for their group to pay more attention to the training of the newbies ,as what a shame to have one barista/waitron ruin what otherwise should have been a great experience. Come on Paul! Give them another chance!
