I understand some if what he's trying to say, but he wasn't very tactful about it.
In my experience I think Irish staff appear friendlier (may inwardly despise you ) than our Eastern European cousins, unfortunately they come across with a very abrupt manner and appear stand offish and even a bit rude, but hey thats their nature and I get that (inwardly may be lusting after you).
I do like a smiley, polite and mannerly person to order food from or book into a hotel...regardless of where you are from.
