Lower standard of service in Singapore

There were several complaints about the deteriorating standard of service in Singapore. In my view, the main causes are:

a) Dependence on foreign workers who are not familiar with the Singapore environment
b) Over-crowding, leading to congestion and highly stressed workers - leaving a negative impact on service.
c) Managers and owners are too focused on profits, and ignore customer service
d) Customer complaints are being ignored - as consumers are weak.

What are our views? What can be done to improve customer service?
