Charged with the April 14 offence, Justin Philip Witchall (22) appeared before Judge Josephine Bouchier yesterday and pleaded guilty.
He was given a ''three strikes'' warning and remanded in custody for sentence on June 6.
The summary, from police prosecutor Tim Hambleton, said Witchall went to the store about 1.15pm and asked the sole female staff member for four packets of tobacco. When the woman asked for identification, Witchall said he had none and left.
He returned about 40 minutes later and entered the store with the hood of his sweatshirt pulled up over his head and his face covered in an attempt to hide his identity.
Carrying a knife in his right hand, he approached the counter and held the knife out towards the woman, demanding money and cigarettes.
Fearing for her safety, the woman retreated to the back of the store and closed the door.
Witchall then tried to open the cash register in an attempt to get cash.
Unsuccessful, he went to the cigarette cabinet behind the counter, opened the cabinet and removed numerous packets of tobacco which he put into a pink carry bag.
It was believed he took 27 packets of tobacco, to a value of $1286.
Witchall and the pink carry bag containing packets of tobacco were found at a nearby address.
Twenty packets of tobacco were recovered. Seven unrecovered packets were valued at $301.10.
Witchall admitted responsibility for the robbery, stating he did the robbery because he was bored.
