A man groped a woman in a club and punched her friend in the face.
Tony Moore was on strong medication at the time following an operation and said he could not remember either incident.
Moore, a 52-year-old contract liaison agent, of Devonshire Road, Bispham, pleaded guilty to sexually touching a woman and assault.
He was bailed for pre-sentence reports by Blackpool magistrates and banned from entering Rumours as a condition of his bail.
Pam Smith, prosecuting, said a 21-year-old woman was in Rumours when Moore touched her inner thigh on December 21.
When the victims’ friend remonstrated with Moore over his behaviour, he grabbed her hair and punched her on the forehead.
Hugh Pond, defending, said his client had undergone a serious spinal operation three weeks previously.
Moore was persuaded to have a pre-Christmas night out with friends.
He drank three vodkas and shared two bottles of champagne with his six friends.
He was on medication and after drinking the alcohol he could remember absolutely nothing.
He was ashamed of what had happened and apologised.
