Anyone for golf?

An American holidaying in Ireland decides to play golf. He goes to the nearest club, asking around if anyone will join him for a round as he’s on his own. An Irishman walks up and says "To be sure, Oi’ll play wid you.. Tomorrow at 9am... but Oi could be half an hour late."

The American is there at 9am prompt, as is the Irishman carrying a set of left-handed clubs. The Irishman wins convincingly. The American suggests a rematch. The Irishman replies "Certainly. Oi’ll meet you here at 9am tomorrow, but Oi could be half an hour late.".....
