I try to never burn a bridge though, so if you can I would refer them to another agent that you think would be a better fit for them (although if the issue is them wasting your time or something, I would be careful so you aren't just handing a problem to another agent).
You may want to consult with your Broker before doing so and also review any agreement you have with the client. It may require written notice to terminate the agency agreement.
Sometimes a client and agent are simply not a good fit. It does not mean either is a bad person. Some people just do not "click".
I have only parted ways with a client once, and it was hard decision to make. He was a well qualified small investor with whom I had worked with many times. But after a while I realized he treated me more like his personal assistant than the real estate professional I am. The business relationship had become too one sided. I was bending over backwards to meet his needs, and he Never seemed to appreciate my efforts, or have any kind of respect for my time.
My business model is to close an escrow on EVERY client, so to part ways with one was very hard, but it was the right thing to do.
