A pub regular threw a drink over a barman after being asked to leave.
Mohammed Hussein was annoyed because his request to have his drink served in a paper cup to take away was refused.
Hussein is well-known in the pub and has not been barred, South Northumbria Magistrates’ Court heard.
“The incident happened in the Adam and Eve pub in Laygate, in South Shields,” said Paul Anderson, prosecuting.
“It was closing time, and the bar manager asked Mr Hussein – known in the pub as ‘Mo’ – to leave.
“Mr Hussein took exception to this, picked up another glass, and threw its contents over Mr Wilson, splashing his chest and face.
“Police were called, but Mr Hussein continued to be argumentative and abusive.”
Hussein, 28, of Drake Close, South Shields, admitted assault, and he admitted using threatening behaviour, both on May 4.
Kevin Smallcombe, defending, said: “Other drinkers were getting drinks in paper containers to take out, but Mr Hussein’s request was refused, which annoyed him.
“He realises he should not have behaved how he did, and he has been told he is not barred.”
The bench ordered Hussein to pay fines and costs of £155, and ordered him to pay £50 compensation to his victim.
