I'll add that one who is questioning the other as being "a man of their word" might be right in doing so in their own head.
The moment they express that thought in writing or verbally, they lose said moral high ground and become the owner of sour grapes - a whiner. No one likes whinging.
I'm not calling the OP a whiner as this is solely discussion. I'm referring to interactions with negotiating parties.
Nothing is free. One of the earliest lessons in life is: if you try to take something that you have not earned there is a penalty.
