These fruteros are the guys who save me from scurvy. You find them on loads of street corners, selling three bananas, half a papaya or pineapple (ready peeled and in a little bag so you don't drip everywhere) or even a mango, each for about 18p. Marvelous. I get my five a day within 100 yards of the door. And they are delicious.

They are basically wheelbarrow with a bike attached, so if business is slow, they pedal off elsewhere. You frequently see these guys pedalling 30kgs of tropical fruit down a 6 lane highway. Note the high-tech cooling and shading sytem, and the cutting edge brake.
