Could you have done a trade? Give him one of your accounts next to one of his if you had one. A win-win. Is this kind of thing ever done?
When it benefits you, then yes. For example to tighten your route. In this scenario nothing is owed to the other LCO. But just to humor you lets say you give him one of yours and then the lady cancels on you too. Now he has your customer and you have squat.
