Crooks continue to prey on San José stores in broad daylight.
Tuesday the stickup happened at a juice outlet on Paseo Colón where some 10 customers and staff were surprised by a man with a gun. A companion waited outside on a motorcycle, said the Judicial Investigating Organization.
Judicial agents said that the two men initially entered the store as customers and then one man returned shortly before noon.
The gunman took the possession of all in the shop and got away with an estimated 50,000 colons, about $100, said agents.
The downtown has been the scene of a string of store stickups but this appears to be the first time that customers were involved.
