You should not penalize an agent for doing a good job. If your agent was able to produce a buyer offering more than any other agent, that would be indicative of an agent doing a great job. It also is a lot of hard work.
I would suggest you not try to nickel and dime the agent, if you need more money then just give the buyers a counteroffer. However, based on the previous questions you had asked and what I know about your situation, your best bet may be to just take the deal!
Remember, that once you accept the offer, you then have to get into contract, hopefully the deal gets to that point! If I can be of further assistance please let me know. Good luck!
