that's just negotiating...
That's being cheap. I met a guy half way once to sell him a cheap wheel chock. Keep in mind only 15 miles from my house cause he didn't want to go 30. When I got there he asked me to knock off $10 for his time and gas. I said sure if you add $10 for my time and gas. He laughed and thought I was joking. He was only paying $30 for the stand to begin with.
Or how about the people that agree to a price over the phone and when they show up they low ball you. grr
