All of it goes down as customers mill about the store.

A man picking out a bottle of wine is seen watching the robbery.  He pretends to walk out of the store only to walk back in and approach the man with the knife.

The wine bottle-wielding crimestopper smashes the bottle over the man's head.

Obviously stunned, the unsuccessful robber quickly runs out of the store.  Police say the same man is suspected of robbing two other stores within hours of this incident.
