A row over two pizzas in a kebab shop ended with a customer punching a member of staff.
Paul Murphy of Kinoulton Court in Grantham admitted common assault following the attack at Best Kebab in London Road in Grantham.
The court heard how Murphy, 43, had been out drinking since 10am and had between 10 and 12 pints prior to the assault taking place.
The trouble began when Murphy was asked to pay £9.70 for two pizzas but insisted he had already paid.
Jim Clare, prosecuting, said Murphy became “violent and abusive” before being told to leave.
Murphy then swung a punch at a member of staff, which missed.
Mr Clare, reading a statement from the victim, said: “With help from some army guys I managed to get him out of the shop but he then started kicking the glass at the bottom of the door.
“I opened the door and that’s when he hit me in the back of the head.”
Rob Arthur, defending, said Murphy “does not dispute the account” but said that when he was pushed out of the takeaway he was also attacked.
Mr Arthur said: “He informs me he was kicked and I have seen quite a significant injury to his back that he bares to this day.”
Mr Arthur said that as well as the alcohol, Murphy was also wearing a morphine patch to help with arthritis.
Mr Arthur added: “I don’t believe he is supposed to have alcohol while on morphine but he did.”
Chair of magistrates’ George Hoyles said: “We would suggest your recollection is not quite as great as you might have thought given you drank 10 to 12 pints of Jack Daniels and whatever else it was.”
Murphy admitted common assault and was fined £73 and ordered to compensation of £60 to the victim.
He must also pay costs of £60 and a £20 surcharge.
