my experience too...
you've done your homework.

It might also be worth mentioning that India was the site of one of the worst, if not the worst, unnatural (man-made) non-military disasters in history - the Union Carbide "incident" at Bhopal.

It might also be mentioned that arrest warrants are still pending for the then-CEO of Union Carbide, Warren Anderson, and abandoned chemicals at the site still contaminate the drinking water.

This by way of saying that Americans and American corporations may be viewed with some distrust in some parts of India like, oh, Bhopal.

Or maybe not.

I worked for Ondian companies for a few years, have Indian friends, and have visited India a couple of times.

It is a little interesting to read the quick takes on this complicated topic.

Regarding Indian politeness.... there are a few points to keep in mind here. The Indians that we typically run into in the USA are the cream of the cream. Also, these workers are reacting to us as their customers in a customer is always right sort of context. Beyond that, there is a built in sort of resentment/deference dynamic for whites, their former colonial masters. I can assure you that if you actually worked for an Indian comapny, you might well have a different exposure to their attitudes.

Here is one story....
While I was visitning India for work, I went out for drinks in the evening with some colleagues. We had a driver (which is common). Upon arriving, the driver was told to wait for us, we would be back at about 10 pm. The driver looked uncomfortable. He had not had a chance to tell his familiy that he would be late. Anyway, along about 10:45, I was getting nervous because I knew we had told the driver to wait till 10pm. I thought at least we should send someone to update him on our plans. When I suggested this idea.... my colleague laughed dissmissively.... He said something like.... "Don't worry about it, he's a f'ing driver, it's his job to wait for us."

Another guy I worked for collected the passports of his employees.... just to make sure they would not run away and join another company. We routinely invented projects to fill out a resume with the experience required to get a technical job.

In December 1985 the New York Times reported that according to UCIL plant managers the hypothesis of this route of entry of water was tested in the presence of the Central Bureau Investigators and was found to be negative.[16] UCC also maintains that this route was not possible, and that it was an act of sabotage by a "disgruntled worker" who introduced water directly into the tank.[17] However, the company's investigation team found no evidence of the necessary connection.[18]

India retains position among the world's most corrupt nations

Devdutt Pattanaik takes an eye-opening look at the myths of India and of the West -- and shows how these two fundamentally different sets of beliefs about God, death and heaven help us consistently misunderstand one another.
