The manager tried to use the display stand to defend himself after the man attacked him.
"I tried to protect myself and I was trying to hit him with the stand and he got angry," he said.
"He smashed me with the stick and it broke in half. He had a longer stick and he was faster than me."
The man also smashed a computer screen in his frustration before escaping empty-handed out the front door and running down a nearby alleyway.
The manager was later taken to hospital for a checkup but was discharged soon after and left with a bruised and sore back.
The attack left him shaken and adamant about the importance of staff not being alone in stores.
"There should always be two people in most of the shops. It's not good safety for the shopkeepers [to be alone]."
Witness David Mackenzie was driving along Cameron Rd toward the city when he saw a man with a piece of wood run out of the store.
"His mannerisms and the way he was standing when he came out of the dairy and the way he bolted looked quite suspicious. My instant reaction was, 'this looks like a robbery'."
The man ran off through alleys between 10th and 11th avenues heading towards the city. He was last seen running down 11th Ave near the Mad Butcher.
The man is described as skinny, wearing a black balaclava, a large baggy camouflage jacket with a hood, black combat boots and blue skinny jeans.
