In this part of continent 'India' bargain happens around everything. No matter how much you are honest in pricing the customer or how low you quote your price majority of consumers always think if they can get more for much less. Even if you offer a free stuff chances are you will be taken for granted. And you cannot control it. If you are a seller you cannot control the buyers behavior. But yes you can control the sellers behavior. No, not by changing the sellers attitude but by changing yourself.
