The market dictates this.
Like many old towns in Europe there is practically no space to put in a giant hypermarket and till now Carrefour hasn't done well with its small stores while Lidl and Aldi have managed to get some better positions in heavily populated residential areas.
So, rather than having clients go to the competition because driving to the outskirts of town is a pain in the ass in the afternoon, they went this way, turning more into something Amazon-like.
This is where the problems start, how long can the chain trace with accuracy products.
Is this Chorizo made with Spanish pig meat? Or it is made in Spain from meat from Italy, bought from a slaughterhouse in Slovenia, from a pig raised in Poland but bought as a young from Denmark and fed food imported from Germany.
And it might sound like an exaggeration but my family does own a farm and although we sell those to local slaughterhouse I've heard even worse and longer chains throughout the EU.
Yesterday I paid for something though Coingate.
They needed 6!!!! 6 god damn confirmations and I timed my tx so fabulous that it went in the mempool right after 3 blocks were mined in less than 10 minutes.
It took 2 hours, imagine this when shopping....
