At the end of a long working day, we all want to go home, but for this man, leaving everything as new was a priority. It is impressive to see how many of these workers keep these machines last for so many years thanks to their maintenance. I remember seeing that man pick up and clean that machine for a long time until everything was spotless for his next day at work. He along with his colleagues do an excellent job with it and that is why people like me can spend hours admiring these amazing machines.
