Anthony Blaydes,(28), of Links Avenue admitted assaulting Adam Golby by beating when he appeared at Boston Magistrates Court on Wednesday, (May 30).
Prosecuting, Paul Wood said Mr Golby, who is the landlord of the Montalt Arms in George Street in the resort, was called down into the bar on May 6 because someone had come to see him.
There he found Blaydes, who he had known for about five years, who had just bought himself a pint of lager.
Blaydes said to him: “Why did you give me the evils this morning,” and when Mr Golby looked puzzled, said: “You mugged me off”.
Mr Golby told him he didn’t know what he meant at which Blaydes slapped him in the face and asked him to go outside with him.
The police were called and Blaydes, who was said to be drunk at the time, was arrested and he told them Mr Golby had been staring at him and that he had deserved the slap as he had told his partner to leave him.
Mitigating, Michael Alexander said Blaydes, who had a previous conviction for assault, had been out of trouble for two years.
He said Blaydes’ partner of eight years had recently split up with him and he was not in a good frame of mind on that day.
“He was in a bad place,” said Mr Alexander.
“He thought that in some way Mr Golby was responsible for his break up because his partner had hidden from him the fact she had been working in the pub.”
He said Blaydes now knew he was ‘completely wrong’ and had tried to apologise to Mr Golby.
“He accepts it was entirely his fault and he got it wrong,” said Mr Alexander.
The magistrates fined Blaydes £150 and ordered him to pay £115 in court costs and charges.
