Even before he began pacing around and yelling abuse, staff had called police.
Tuwairua told the victim — a 28-year-old employee who was eight months' pregnant — he would retrieve a shotgun from his car and "shoot the place up".
He told the woman he would blow her head off in the store, the court heard.
Tuwairua then decided he would help himself to a refund, reaching over the counter, attempting to gain access to the till.
When that proved unsuccessful, he left with his associate but yelled that he would return.
It was two days before police tracked Tuwairua down to a Fairfield address, but despite the time that had elapsed since the burger rage, the defendant remained belligerent.
When officers told him he was under arrest, he repeatedly claimed innocence, and when they tried to handcuff him he twisted his body to evade them.
A struggled ensued, during which Tuwairua "lashed out, kicking and biting", and his resistance was only overcome when police used a Taser and pepper spray.
It was not the defendant's first experience of such treatment.
Six months earlier, police were called to a Dunedin boarding house after Tuwairua's tenancy had been terminated and he reacted with similar fury.
After smashing holes in a wall he made extensive threats and pretended to shoot at officers with finger guns.
On that occasion he encouraged them to Taser him but was eventually subdued with pepper spray.
Judge Josephine Bouchier yesterday said Tuwairua had now racked up 45 convictions for violence and threats.
She sentenced him to six months' imprisonment on charges of threatening to kill, intimidation and resisting police.
Because of time spent locked up on remand, Tuwairua will be released next month.
