Food, the produce department

About every two blocks is a store selling produce and maybe a few other things.  I can't figure out how people choose a store since they seem the same to me.  I assume they base it on location or a recommendation from a friend.  I sometimes go to these stores and I sometimes go to the grocery store, which is close to our apartment.

At the store it is serve yourself,

preferably using gloves found in the metal box.

Then take your bag over to the scale and press the number
(found on the sign, see first picture).

Maybe these are a different kind of yam or sweet potato?

You can also look at the picture or name.

After pressing the picture/name/number,
the machine will produce a sticker with the price.
f.y.i., tubérculos = tubers

Check out the celery!!

During the week there is a changing display of fruits and vegetables.
When we arrived late on Saturday a lot of foods were sold out, including from the display.
It pays to shop on Friday or join the crowds on Saturday.
