just seeing something anecdotally that isn't cultural or if what I'm about to describe is cultural. In my experience, Indians view every time the subject of money comes up as an obligation to reopen negotiations and get a better deal.

It's to the point where I'm considering not even dealing with Indians at all because the constant renegotiation wasted so much time. Either that or I need to figure out how to explain that I'm only going to work with them if they realize that the deal is the deal and I don't want to take time renegotiating unless something really has changed or some significant piece of information really has come to light.
