Once I was at a business dinner where they were discussing an important deal. Everything was tense, everyone was trying to look as professional as possible, and at some point the conversation became too dry. And one of the participants came with a girl who, as it turned out, knew a lot about the topic and knew how to keep the conversation going. The atmosphere immediately became lighter, people relaxed, and the conversation flowed more naturally. In the end, he was the one we signed the contract with. I think the right companion can really influence the course of negotiations. Has anyone experienced this?
