An alcoholic admitted pushing another man in a row.
Gene Fisher, 37, of Amber Terrace, Lynn, admitted assaulting Kieran Liffen at a home in the town on September 25.
Prosecutor Giles Beaumont told Lynn magistrates yesterday that Fisher appeared very drunk and that the two men argued over a former partner.
Mr Beaumont said Fisher raised his fist and pushed Mr Liffen to the chest.
George Sorrell, mitigating, told the hearing that Fisher had gone to see his former partner and argued with Mr Liffen, who was one of three men at the house.
Mr Sorrell said Fisher was an alcoholic and is seeking help from the Norfolk Recovery Partnership.
Mr Sorrell said: “It is not very nice to wake up in the morning and feel ill and the only way to overcome that illness is to have another drink.”
Magistrates fined Fisher £80.
He was also ordered to pay £150 court charge and a £20 victim surcharge.
