I would expect no less of a Broker doing his job of supervising his agents and protecting his Brokerage. So are you asking if your split between your Broker should be adjusted? That is between the agent and the Broker employment agreement. If there isn't anything in the agreement, I would take my Managing Broker out to lunch, thank him/her and pick their brain on how to refine my skills as an agent.
I guess you feel that your broker coming to your resque with that seller should be rewarded?
I agree with other agents that brokers are there to support you, and this is not necessary.
However, a thank you card and possibly a small gift (something funny or chocolates) could help you feel better about your broker's listing saving efforts.
Hope this helps,

Brokers in Charge are there to motivate, educate and support, not shake down the agents their responsible for.
Why should the broker receive a "higher: commission for assisting an agent?
Doesn't the Broker get an override of the business that is done anyway?
It's in his or her best interest not to lose an office listing.
I suppose I don't really "get" your question!
