Well, quite - he just didn't seem to pay any attention, but you didn't need to be an expert in negotiation to realise Jim could have gone quite a bit higher. And Tom shouldn't have said anything until Jim had stopped coming up with new points.
If Jazzer's previous drug history is being made relevant, makes you wonder if he didn't have any negotiating skills from those days dealings.
