Operators of a roadside pantry in the SA's Riverland have lost hundreds of dollars due to theft and vandalism.
Roadside stall operators say they are dealing with more theft.
Once the pantry in the Riverland is fixed, it will be cemented into the ground and the money box reinforced.
Roadside stalls are a tradition in regional and rural Australia, and the honesty payment system is a big part of the experience.
In South Australia's Riverland, about 80 kilometres out of Adelaide, Michelle Carter and her family started selling goods at the end of their driveway in August.
Every Saturday morning, they restock the 100-year-old meat safe with everything from sauce and sourdough to cupcakes made by Ms Carter's 15-year-old daughter.
The incident occurred in broad daylight while the family was fencing in a nearby paddock.
Most upsetting to Ms Carter was the damage done to the pantry, which the family had carefully restored.
For her 15-year-old daughter, the effort of baking fresh cupcakes on Friday night had gone to waste.
Adelaide Barbaro gave up trying to sell flowers from her own roadside stall after just three months following a series of thefts of both product and money.
Though it was not the right business model for her, Ms Barbaro said she did not regret starting out with a roadside stall.
Though cash will still be an option for now at the 90 Acre Pantry, if there was another theft Ms Carter said she would move to only accepting online payments.
