A friend of mine used to be a sales engineer. On business trips, he was assigned an entire team of lawyers, each with a different specialization. His clients were also equipped with the same.
In the negotiation process with deals reaching hundreds of millions of dollars, the lawyers audited every letter, word, and number. He first joked that the lawyers just place roadblocks on everything, then shared:
Their job was to make sure we stayed out of trouble.
And if we got in trouble, their job was to get us out as fast as possible.
