Do you like this Sicilian Greengrocers? If you look carefully, you can see its wheels.
His weighing scales are hanging off the brake light. They hold them up with one hand and slide the ball weight along a metal bar to get the weight of your fruit and veg.
if you query the sweetness of their merchandise, they will instantly chop a fruit in half and force you to eat it on the spot to prove its quality.
These mobile greengrocers can be seen everywhere in Sicily. I have been meaning to photograph one for ages, but was beaten to it by my friend Brita. Thanks for the picture, B!
