After inquiring about a used car I later received a follow-up call (not sure on salesman's name) and was immediately met with hostility from the salesman after/while I questioned the price and then explained my reasoning, where then after being asked what my line of work was, I was told to "stick to that because you know nothing" where he then promptly ended the conversion. Not really a good look for him or the dealership if that's how he speaks to customers without even trying to make anything of my interest in the car by countering or saying what he could offer at all.
