What cultural faux pas should I try to avoid making in Killarney?

"In Killarney, it's important to avoid making jokes or negative comments about the Irish language, history, or culture, as this can be seen as disrespectful. Don't compare Ireland to the UK, as this can be a sensitive topic due to the historical conflicts between the two. Avoid discussing religion or politics, especially the topic of Northern Ireland, unless it's brought up by someone else. It's also considered rude to refuse an offer of tea or food, as hospitality is a big part of Irish culture. Don't imitate the Irish accent or use stereotypical Irish phrases, as this can come off as mocking. Lastly, remember to always say 'please' and 'thank you', as politeness is highly valued in Ireland," mentioned another expat when asked about moving to Killarney, Ireland.
