This is a direct result of huge workforce employing here, with out the basic necessities. They are also humans, deprived of having normal way of life as others. Mainly they are away from their family. If we forget the other stuffs such as salary , housing condition etc.
We are aware about the people, who are working in shipping, behave when they sail into a harbor. Perhaps they will be away for very short time.
SO you can imagine the plight of these unfortunate people, who lives years and years away from their basic physical needs, How they will feel, when they come into town...??
Simply, this ogle and family day is a direct result of the above.
