To be honest with you I don’t know if this is purely an Australia thing. I’ve been to nearly 60 countries world wide and I don’t recall seeing this custom anywhere else.
Side of the road. Middle of nowhere. A little table with a cover set up offering local produce for sale. But nobody there selling. It’s all based on an honesty system.
The price is written, a little box is left on the table and people take their fruit or vegetables (sometimes horse poo!) and drop their money in the box.
The system is totally reliant on the customer being honest. I’m sure there must be people who take stuff without paying, or not paying enough. But the system must work overall because it happens everywhere.
Up here in far north Queensland the produce for sale is likely to be tropical in nature – often fruit. Mangoes, pineapples, bananas, pawpaws. Every kind of delicious tropical fruit under the sun, and all straight from the farm and a lot cheaper than the supermarket. Win win.
