Philip Fitzpatrick (32) admitted causing a breach of the peace in the incident following Dublin's All-Ireland Football final victory this year.
Dublin District Court heard he had told investigating officers: “I pay your wages”, despite the fact that he was on the dole.
Judge Alan Mitchell fined him €250 and made the order excluding him from pubs, remarking that he took a “dim view” of Fitzpatrick's attitude to the gardai.
Fitzpatrick, a father-of-four of Grove Road, Finglas, pleaded guilty to using threatening, abusive and insulting behaviour at Phibsboro Road on the morning of September 23 last.
Garda Conor Cadogan told the court he was called to an incident outside the Sunnybank Hotel in the early hours of the morning.
The defendant was in an agitated state and directed “a number of abusive comments” at the gardai before he was arrested.
He had previous convictions.
The court heard Fitzpatrick had worked with people with disabilities, was a gym instructor and was hoping to get work in that role next month.
He was “someone with good prospects” but was currently unemployed and in receipt of €188 per week in social welfare.
“His attitude to the gardai left a lot to be desired,” Judge Mitchell said.
Garda Cadogan said Fitzpatrick had told officers that he earned more in a week than they earned in a month and that he “paid their wages”.
“It is difficult to see how you pay the wages of the gardai if you are on social welfare,” Judge Mitchell said.
