The friend and advisor to former Taoiseach Brian Cowen said if he wanted to lobby him it wouldn't have been on a golf course in July 2008.
Fintan Drury - who is also a former non-executive director of Anglo Irish Bank - is before the banking inquiry about meetings he organised between the bank and Mr Cowen.
He said a dinner in April 2008 with the Anglo board was "completely unremarkable" and that the golf game and dinner that summer was about getting perspectives about the economy in general and not banking.
Mr Drury, however, said the conspiracy theorists about the golf game are wrong.
"For me, the idea that the meeting, the golf, and the dinner in Druid's Glen was part of some conspiracy to capture the support of Brian Cowen for some kind of imagined need that Anglo had in July 2008, is lacking in credibility."
He said the meeting lasted about two hours, during which the group went through an agenda created by consultant Alan Gray - which did not include banking affairs.
