This is one of the typical Amazon Arckets. In Hego Euskal Herria, we've seen yellow and blue. Some are called a hub and others locker, there will be some nuance running, but they are presented in Spanish with an empty message:
They are for those who have domestic pick-up schedule problems, you can specify a type of locker or pick-up point, and when Amazon leaves your order on it, because it goes with a code to the pickup store, puts the code into the machine and the corresponding pickup will open.
Now that someone has manipulated, besides being reminded of the damage Amazon causes to local trade. We can tell you social hacking or troll.
