Over the last few days, the image of ¡Madrid Limpio! (Madrid Clean!) has suffered some tough attacks by the cleaning service of the city Metro system. The first day I went down to the underground since the stroke started, I couldn’t believe what I saw. It looked like a late 1970’s movie set on the rough streets of New York, where rival gangs were fighting. Infected. It’s bizarre to realise how dependant we are of invisible services. These services have become strong and visible this week. We depend on services we don’t know anything about. On the other hand, we see how much waste we produce in the Metro everyday.
