Dishwashing Footwashing

The guy has set up a fast food and beverage stall on the pavement opposite the hospital. He serves these items to resident doctors, patients' relatives, visitors and passers by. Since the stall is on the pavement, there is no supply of running water. So he keeps water in a container and uses it to clean dishes and glasses used by his customers. I got stuck in traffic next to his stall and had an opportunity to watch his work. A couple of customers had food and fruit juice at his stall. He dipped the dishes and glasses in one bucket containing very turbid (nearing on muddy) water. Then he dipped them into another bucket containing less turbid water. Then he placed them on his table in the stack to be used by future customers. Then he happened to step into mud nearby. He took out a glass of more turbid water from the first bucket and poured it on his foot. Then he took out a glass of water from the bucket containing less turbid water and poured it on the same foot. I think the guy has integrity. He treats his customers hygienic and his feet equally shabbily.
