I agree. Personally, I'm more sick of the culture of bargaining and haggling over increasingly small, pedestrian items that has gained a lot of fashion in the recession, even among people for whom it is not a financial imperative. It was a movement with a lot of momentum even before the recession, though, so there must be some other more enduring dynamics at play, too, not just cyclical stuff.
There's a social cost to making an ass of yourself arguing +/- $0.30 on a loaf of bread, so I don't do it. And--I jest not--I get chided by "frugal" people for not spending a half hour going through my pile of 50+ coupon clippings in front of the register in the express lane, ten people waiting in line behind me be damned.
Nobody in the startup scene here likes a customer that rides them about price no matter the discount, and appears to be fixated solely on price and not on value. Nobody likes the message that sends about the customer's priorities, their character, or the value they attach to the product or service. There is a moral and a psychological valence to the whole thing. It's off-putting, because it says that you don't realise that sometimes there is more to life than cold, rational economic calculus. So why do it to others?
Negotiating big-ticket items like salaries, houses and cars has always been okay in this culture, and there are considerable practical reasons to do it; thousands of dollars are on the line, and the people on the other end of the table have a pricing structure and a sales methodology designed specifically to maximise gains on people reluctant or unable to negotiate. Obviously, I'm not saying you should allow yourself to be screwed for the sake of eschewing confrontation.
However, at the risk of sounding culturally chauvinist, as a Soviet immigrant, one of the things I have always liked about the US and for which I have taken pride in my adopted homeland is the fact that we're above petty bazaar culture here--haggling for the sake of haggling, or being obscenely preoccupied with price. Let's not lose that. Those of us from other cultures that have fewer compunctions about wheel-dealing in petty crap know where that leads, and it's a really detestable trait when not mandated by the necessities of poverty.
