You would see these people anywhere cetral town. Wherever you go they are there, these low class people work very hard by doing some back breaking jobs and earning lilte money. She perhaps earns what you pay for a beer for a day of hard work under intensive heat from the sun and radiated from the tarmac. Walking around all day long with stuff on the back or hung in the front of their bodies. Customers mostly shake their heads when offered stuff from these poor traders.
Sad but that is part of life, what can you we do?
