In a pub in London a few years ago, an English guy asked if he could take one of the stools, I said it was stuck to the floor (it was fixed to the floor) and of course he thought I was being smart with him and combined with the accent said "you Irish are smart fockers". I laughed it off as he was too stupid to check that the stool was actually fixed to the floor
Our history of drinking preceeds as abroad, every nationality I have met mentions it, one from Austria actually thought the entire nation at lunch time goes to the pub and drinks all day, probably some truth in it but I corrected her in any case
