Either This One's On The House Or I'll Give You A Whippy, Mister.

How did that old saying go? I scream, you scream, we all beat the wholly christ out of the driver and run off with his money when he refuses to give us free icecream?

The offender was turned away when he asked for a free ice-cream.

However, when the driver hopped in the front seat to drive away the man leapt in through the service window and threw a bottle at him, Detective Darryn Gabb said.

He then hit him with a flurry of punches which left the victim battered and bruised, Mr Gabb said.

The offender asked where the till was and stole about $550.

Police are still looking for him and the Mr. Whippy (seriously, that's what it's called) owner the driver works for has offered a $100 reward for any tips leading to an arrest.
