About five years ago I worked on a buy-sell deal, representing the buyer. Time goes by and I get a call from the seller, asking for help with one of his other businesses.
I got the call because he respected the way I handled things. He knew my objective was a win-win deal. (This is an example of why I tell clients their legal bill is dependent on how well the attorneys play together – some play well and others always want “everything.”)
If on every assignment you treat everybody fair, your short and long-term results will be great.
