A Supermarket Statue? Why?

I'd sure like to know the story behind this statue. It's a statue of a shopper... placed in front of a small supermarket, in Vila do Conde, Portugal.

This is so strange. Usually statues are monuments to heroes, artists, well know people. But here we have a monument... to the average supermarket client? Eh?

Why was this built? Is it just a mere decoration?

Maybe someone from Vila do Conde can explain it because I... I am very confused.

Edit: Thanks to @mafaldation, we now know that this is a Tribute to the Farmer of Vila do Conde.
