Dannevirke businessman Kim Phelps is fed up after the fifth break-in at his High St premises in four years.
"I've got the most finger-printed till in Dannevirke," he said. "But the ironic thing is that there isn't any cash kept here on the premises, just as the signs all around the building say. In fact, there's nothing here to take unless the thieves want some jam or a natural health magazine or two."
Of the five break-ins, three have occurred since November.
"There was no cash there to be taken in all three of those," Mr Phelps said. "I'm thoroughly sick of being targeted, with the cost of repairs adding up.
"I've got insurance but it would cost me more to make the claim than it's worth, so it's been five times I've had to pay for repairs myself," he said.
