Generation Kia

Customer service does not exist anymore; the sales associate I dealt with today was immature, unprofessional, and rude. I was told That I have champagne taste with beer money and was told the price is the price and there is no negotiations. Mind you the car I was looking at was below 20,000 and nothing fancy. I felt I was willing to go as high as I could afford (living on Long Island) and I was told no not good enough and that there was nothing else this unprofessional sales associate could do. Also when we were being shown the car he was smoking his vape cigarette and when we left he did not even shake my hand as I thanked him for all his time.
