I live here in Singapore for the past 10 years. As you, i have
also wondered why so much indians gather there on weekends. I don't
know the answer until few months back. Though, i am Indian, we are
creamy (call ourselves) layers who does white collar job and would
hardly go to Little india except to buy our grocieries. But, the
people who gathers there are blue collar workers, Supporting my
friends business, i had a chance with them to interact and most of
them live in the dormotories in Tuas, Jurong. Most of the week,
they eat their self prepared food (though, it will be horrible,
they have no choice), during weekends, they can spend few dollars
on so called good food from little indian restaurants and most
importantly coming there to interact with their own villagers who
work here. The reason for gather is to pass on information back to
village friends, family , to send electronics good and to gather
information about the happening in their and neighbouring villages
back in India.
Though, it may seems to be a gathering, if you notice, there
will be small pockets of people, most of them are from same
villages and neighboring villages.
It is true that it can be irritating when you want to glide
through their staring eye (if you are with your wife or girl
friend), but, we have no choice unless avoid weekend evenings. This
is not the case in India, but, here it is different, because too
many singles at a same time.
Ya, most of them are uneducated construction worker. what
u expect?
