Not until I visited Vietnam. We hit it off with our hotel manager, hung out a bunch. He told us it's part of the culture, you're supposed to do it. You're going to get offered the price that's three times what's considered reasonable. The third offer should get it where it's supposed to be and that's where a reasonable person stops haggling. He said some very unpleasant people always take it too far and people don't want to do business of any kind with people like that. He also said there's a different price for foreigners than there is for locals. When we'd go out with him, he'd insist on paying, ostensibly because he'd get that local price. Of course, it's more complicated because we eventually learned they get kickbacks for bringing customers in.
