A Dutch student hurled a cappuccino cup into a hotel manager's face as he tried to break up a catfight in a luxury four-star suite, a court heard.
Muna Guled (pictured), 22, launched the missile amid a scene of flying plates and cutlery at what was the Thistle Marble Arch hotel in Bryanston Street, Marylebone, west London.
Guled was left bleeding after being struck in the head with another coffee cup and hurled one back during the melee on 14 November 2015.
Hotel manager Herkus Milasevicius was hit in the face by the object when he hurried into the room to intervene, Westminster Magistrates' Court heard.
Prosecutor Denise Johnson said: "There were two people having a fight, they were throwing items at each other.
"This defendant threw a cup and it missed the person she was aiming for and hit the manager, who is the victim in this case."
Milasevicius suffered a cut to his head but managed to break up the fight at the hotel, which since been renovated and reopened as the Amba Hotel Marble Arch
Johnson said: "He says that he was trying to intervene. He saw this defendant throw a cup at the larger defendant.
"This cup hit Mr Milasevicius in the head just above his eye and he had a cut, a small cut just above his eye."
She added: "The victim says in his statement that he realised he was bleeding, he got a towel to stop the bleeding, it doesn't appear he went to the hospital."
Guled was taken to St Mary's Hospital in Paddington where she receive stitches to her cut.
She was said to be "extremely remorseful" when she was later interviewed by officers at Charing Cross Police Station.
Johnson said: "She said she had had an argument with another girl, they were throwing items at each other."
Hotel staff had allowed the other woman to leave the hotel to calm the situation and she was not charged with any offence.
Guled pleaded guilty to one count of assault.
Chair of the bench Paul Brooks said: "What happened that night was totally unacceptable, you threw a cup which injured somebody who was coming to you aid.
"He was a member of hotel staff so he was serving the public and that aggravates this matter."
Guled, who is studying health and social care at London Metropolitan University, has one previous conviction for a similar offence on 8 April, the court heard.
Guled, of Market Place, Ealing, west London, was given an eight-week community order with a curfew between 8pm-6am and ordered to pay Milasevicius £150 compensation.
