People tend to believe and act on the idea that everything is negotiable. As I said before, I have a unique approach to negotiations, as  a former salesman, and I tend to stick by it.

Everything is for sale, but that does not apply all the time to everybody. This is also a quote that could be embossed on people minds. You got a great deal, don’t fuck it up by trying to negotiate it more. I’ve helped you for free, don’t abuse it!

In situations like these, i tend to tell the person either it will cost more or the deal is off. It works.
