I'm Irish and worked as a barman for over 10 years. I don't know what happened to cause an issue with you but neither myself or any other bartender I worked with ever gave a shit about someone ordering a carbomb. We just made them and judged you for ordering a terrible drink
I looked up authentic McCracken and nothing comes up apart from a couple linkedin profiles and baseball player Quinton McCracken.
What did you mean by that?
A quick search shows McKracken is a Scottish surname (wigtown, SW Scotland) that moved to Ireland in 1600s and is the surname of 1 in 223000.
So.. I'm not really sure what they are on about.
