A Monkton man who celebrated New Year's Eve by smashing a glass over another man's head learned on Thursday it would cost him £2,500.
James Johnson, aged 27, was also made the subject of a 16-month prison sentence, suspended for two years.
Johnson, of Tryblith, admitted wounding Luke Phillips. The glass smashed and fragments hit Jade Thomas, scarring her for life.
Johnson also admitted wounding her.
He was ordered to pay Miss Thomas £2,000 and Mr. Phillips £500.
Brian Simpson, prosecuting at Swansea Crown Court, said Johnson had been drunk inside Paddles nightclub, in Main Street, Pembroke, and argued with Mr. Phillips over comments made on a Facebook page.
Johnson suddenly punched him to the face and threw a glass at his head, which caused several cuts.
Miss Thomas, who was standing nearby, suffered cuts to her head and both victims needed hospital treatment.
The court heard that Johnson had been so shocked at what he had done he gave himself in to police the following day.
After his arrest he said he had been drunk and 'saw red.'
He said he had meant to throw his drink over Mr. Phillips and not to smash the glass over his head.
But he added that he did not regret punching him and 'would do it again.'
His barrister, David Williams, said he was deeply remorseful and ashamed. Monkton, he added, was a small community and Johnson had been ostracised as word got round about what he had done.
Judge Huw Davies said he accepted that Johnson had not intended to injure Miss Thomas, 'but that's the trouble' when people start to throw glasses around.
"Innocent people get harmed, not just the intended target," he added.
Judge Davies said he noted that Johnson had previous convictions for getting drunk and fighting in Main Street.
He said the compensation was not intended to value the harm that had been caused.
