A third person, 29-year-old Paula Green, of Weybridge, was sentenced to 15 months in jail for assisting an offender, police added.
DS Joe Easterbrook said: “This was a highly unusual incident where two men in very distinctive clothing attempted to rob a local business in broad daylight.
“The two members of staff working that day refused to be intimidated by the suspects and showed tremendous bravery to challenge the two men and stop Price from leaving the store until our officers arrived.
“Although the members of staff were both very shaken by what took place, fortunately they both only suffered minor injuries during the incident.”
