The Restaurant Ratna Cafe at Chennai Central Station is not serving customers properly. I happened to see today morning(8/4/2016, 5:45 am) at least 50 hungry customers being turned away on the guise of 'no change available'. If these people are pricing the products in such a way that the prices end with the number 5, and do not keep enough change even right in the morning, then why should they have their stall there? At least some other more professional restaurant can be given the chance. The Chennai Central Station authorities should insist on professional service to the customers, or terminate their contract.
