Car Buying Sucks!

Why do car salespeople waste people’s time? I was at a dealership looking at a car I was interested in. I had reached out to a few dealers to get quotes so I had an idea before going in. I went to the closest dealer and talked with the salesman who dismissed my offer in hand from another dealer. Told me there was no way and they are losing money. I told him it was fine if he couldn’t match the offer and went on my way. Less than an hour later after leaving, the salesman calls and said he could do the deal so he can earn my business. At this point since I now think he’s a dbag, I tell him I’m not interested and go elsewhere. Had he just done the deal in the first place instead of wasting my time, he would have sold me a car that day.
