During the same proceedings, West Midlands Police said the owner “took no visible action” to de-escalate the fight and no calls were made to the force during the incident, despite at least eight members of staff working.
The stabbed man was taken to hospital to treat his injures, which were not life-threatening, said police.
The hearing was also told how Mr Sahani had not kept records of training or refusal logs, had not offered staff training in conflict or resolution management, and had taken “no issue” with a potential fault with CCTV cameras.
The licensing committee ruled the incident took place due to “poor management”.
Mr Fellows said Mr Sahani was a young father who had never experienced such disorder and it was the first time he had to deal with a fight at the premises.
