"My friend and I called the police and realised they locked us out."
"We then just ran out the back of the house and back in to the front of the store to find half of our cigarettes and tobacco gone."
By that point the duo had already disappeared with about $4500 worth of cigarettes and tobacco.
Mr Singh said they didn't take any cash as they were unable to open the till.
Neither of the women covered their face so police were working through the footage to identify the offenders.
"It was pretty scary and all happened very fast I was just lucky I was not hurt."
A police spokesman said the pair ran out of the store and got into a vehicle which had been parked outside the store facing the wrong way.
"The vehicle was possibly blue."
This was the first aggravated robbery Mr Singh had faced a part from an attempted snatching a couple of months ago.
He said it was pretty frightening but it was back to business as usual today.
"We opened this morning and I am not too worried anymore it was just scary at the time."
"I was lucky my friend was nearby and the owners lived just around the corner, as when they heard they came around straightaway."
Police are appealing for any information and would like to hear from any witnesses or anyone with information that may help the investigation.
