BAR owner Justin Hudson suffered a fractured jaw when a knife-wielding thief robbed him of £10,000 in takings.
Mr Hudson, who owns Butlers Venue Bar, in Eastgate Street, was taken to hospital after the violent attack, which he described as the "most terrifying experience" of his life.
It happened at 3.30pm on Sunday at a bus stop near Fever nightclub, in Eastgate Street.
Mr Hudson, 36, said: "It was horrific. I've run my bar for 16 years and nothing like this has ever happened to me.
"They fractured my jaw and I'm in agony with it.
"I will take this to my grave. It was definitely the most terrifying experience of my life.
"We were taking the money up to the bank and my supervisor had it stuffed up his jacket.
"A man was waiting at the bus stop and leapt out and attacked us as we walked past. He had a hoodie and all I could see were his eyes and nose. He was saying 'give me the money, give me the money'.
"He grabbed the money and then he was gone.
"You never believe these things are going to happen to you."
Mr Hudson was hospitalised for several hours after the attack.
Friends were yesterday wishing him a speedy recovery.
Pal Reece Baker, who worked as a barman for him a decade ago, said: "He's a nice man and a good friend.
"We are all in complete disbelief. We're all lost for words over what has happened."
The attacker was around 5ft 6in and was wearing a grey hoodie, grey jogging pants and red and white trainers.
Detective Sergeant Tracyann Curtis said: "We need to hear from people who were close to the bus stop and may have seen something.
"Witnesses may not have fully appreciated what was happening at the time but we would ask anyone who thinks they were there when this happened to call us."
