A convenience store worker has been rushed to hospital after being shot in the elbow by a masked robber in Melbourne.
The 40-year-old 7-Eleven worker was ambushed by the gunman after unlocking the door for a customer about 4.30am on Wednesday.
The attendant had been mopping and ran to the back of the store but was shot in the elbow, police say.
"He's extremely shook up and extremely upset by the incident," Inspector Michael Daly told reporters, adding that the victim was taken to the Alfred Hospital with non-life threatening injuries.
The robber had been after cash but fled wearing a beanie, black and white bandana and a hoodie and tracksuit pants.
It's believed he tried to hold up a Springvale South service station less than two kilometres away 15 minutes earlier.
The Australasian Association of Convenience Stores was quick to link the two attempted robberies to an increase in tobacco taxes.
"Tobacco has become a very valuable commodity; tobacco first then cash. If it was not taxed so highly, it would not be so attractive to violent robbers," chief executive Jeff Rogut told AAP.
Police said the bandit was after money at both stores but failed to make off with cash.
