Last Christmas Wham
Two men entered the store on Wimborne Road just after 4pm yesterday demanding cash.
When a member of staff refused, they hit him over the head with a blunt object and ran off in the direction of Pinewood Road.
The worker had to be taken to hospital for treatment to a head wound but luckily wasn't seriously injured.
Police in Bournemouth say both men were white, one was wearing light coloured trousers with a blue t-shirt and a black and white baseball cap.
The other man was wearing green combat trousers, a green shirt and a white baseball cap.
