IIRC, atleast the 'sink test' was referred to in some Bollywood movie, where a character who was prescribed several battery of tests, was suggested by another to first consult 1-2 more doctors, as it would've been detrimental to blindly believe the doc's prescription and possibly rid himself of his money for nothing quickly! a fraud going on from a long time. and this same ilk slyly accuses even rather scrupulous, non-glamorous practitioners benefiting general populace in a non-mercenary manner, of esp. other forms of healing & medicine, of 'probable quackery & malpractice'! bloody scoundrels, can't digest the fact that dedicated people can still help others heal without prostrating themselves before 'kanchan'! these pests are several steps ahead of even actual quacks! i don't understand why this country cannot and would not instill the fear of death in such mercenary-docs, food adulterers and the whole wide spectrum of scum!
some time back, a man going to his office in morning riding a bike at Borivali was hit by a lorry or something. some passers-by took him to a nearby hospital. there, they found themselves to be short of the admission-fee by a couple of thousands. even then, the bloody blood-sucking docs refused admission to the injured man, demanding full payment upfront! those strangers who had brought him to the hospital, they said "we watched him die in front of us then and there itself." first of all some people tried to help a total stranger who got injured in a road-accident, which in itself is a feat worth commending, and then THIS happens! thankfully, the registration of that rotten hospital and i think even the licenses of the $h!tbag docs were cancelled! but i would've been very happy had the relatives of the person stormed the hospital and took the docs to task! don't know if that happened later really or not.

amid such negative vibes, there's one strong dose of positivity to be found in a gentleman at Jaipur. can't recall his name. he runs a small hospital from his own money, buys beds, bedding, etc., from his own savings, does a near-perfect job of maintaining each and everything and inspecting them daily, treats poor patients for heavy concessions or for free. needless to say, the locals are absolutely happy and find him to be a Godsend relief!
also reminds me of a doc/surgeon who works and stays at Baba Amte's aashram (if am not wrong), treats the tribals, and takes Rs. 2/- as his emoluments!
