Well, I think it helps to understand that this is a negotiation and there are tactics to it. If you have little actual leverage but lots of time and confidence, it helps to do most of the talking, because you are essentially (politely) repeating your talking points over and over, in the hopes of wearing the other party down. This is basically what politicians and salescritters do for a living, by the way. The conversation in the video is actually rather bad at showing off the bot's abilities (if that was the intent) because the agent gave the caller what they wanted right away and the caller just accepted it. But all good negotiators NEVER take the first offer and usually don't take the 3rd or 4th either. If you really want the best deal possible, you have to keep asking permutations of, "Is that really your best offer?" Or "Can you throw anything else in?" Or "Can you do any better than that?"
