Correct me if I'm mistaken, but Romanians have a very strong haggling tradition. I've personally only been two weeks in Romania, but even in other European countries the Romanian vendors would recognize my wife as Romanian and begin haggling with her in Romanian.
I guess older people do that in farmers market or when trying to sell used stuff - some real estate can be negociated too, but usually the seller mentions it in the ad. Other than that, it's kinda weird to negociate stuff in stores or for services, at least for me, a 30yo male.
