A thug threw a bottle at his girlfriend's face after they argued during a night out in Newcastle.
Drunk Alan Robinson lost his temper with his partner in the Waiting Rooms bar, on Westgate Road, and launched his beer bottle towards her.
The attack was captured on CCTV and the victim was left with swelling and bruising to her face as, fortunately, the bottle didn't smash, a court heard.
Robinson, of Runneymede, Sunderland, was arrested and pleaded guilty at South East Northumberland Magistrates' Court to one count of assault by beating.
Rachael Glover, prosecuting, said the the 33-year-old and his girlfriend of six years were out in Newcastle city centre together on August 15 this year.
The pair were in the Waiting Rooms when Robinson was seen to hold a mobile phone up and point to it before losing his temper.
Miss Glover said: "CCTV shows that there is an argument and the defendant throws a glass bottle to the face of [the victim], which caused significant swelling and bruising to her face."
Robinson was arrested and gave a no comment interview.
Charlie Carr, defending, said Robinson, who earns £30,000 a year, had found a number on his girlfriend's phone, which had caused him to lose his temper.
The solicitor added: "He meant to swill the contents of the bottle on to her but the bottle flew out of his hand.
"It's not right and he's extremely sorry about that. The relationship has continued as this is out of character."
Magistrates gave Robinson a 12 month community order and fined him £259. He must also pay £100 compensation to his victim.
