It is considered impolite to end the call abruptly by saying 'bye' once and hanging up immediately. It is rude not to take off your hat when entering a home, church or pub. The Irish are relatively flexible with their time, so it is generally acceptable to arrive 15 minutes after the designated time.

In Ireland, social etiquette is governed by a culture of politeness and a strong dislike for boastfulness or rowdiness. One of the most common faux pas is "skipping a round" at a pub; the Irish typically drink in "rounds," where each person in a group takes a turn buying a drink for everyone. If you accept a drink but leave before it’s your turn to buy, it is seen as incredibly stingy and rude. Additionally, being overly blunt or confrontational is frowned upon; the Irish tend to use "roundabout" communication to avoid direct conflict. Another major "no-no" is confusing Ireland with Britain or referring to the Republic of Ireland as part of the UK. On a more everyday level, failing to thank a bus driver as you exit or not acknowledging other drivers with a small hand gesture on narrow rural roads is considered poor manners. Finally, being "loud and flashy" about money or personal success is often met with "the slagging"—a friendly but pointed form of teasing meant to keep one's ego in check.
