bad buyer, since you did not prepare yourself proper before going to showroom. two, when buying a car, you go for the best car, engine, look, application and features, why would car sale people gone into the buying equation? why would you care what they think of you when you buy a car? you miss the whole objective.
like with your business now, would you choose not do business , even profitable one, just because your vendor look down on you? i hope you are not the buyer in your business, that will not be wise.
