I am so bad at negotiation. Multiple times it has happened and every time I try and prepare myself and every time i give in too fast. Later on when I look at the deal I feel that I could have made a better deal.
However more than once I have realized that people have cheated or lied to me in the process and I have told them the truth which they used against me in the same negotiation.
‘Bridge of Spies’ teaches you, how you can do it without lying and with greatest of respect.
