Good morning online community, 

I need advice on this. Single new client, no children

When I saw the w2, I knew right away she will not get a refund o maybe a very small refund. I said, just by looking at it, I can tell you they did not withheld enough taxes. She said, ok do it. To make the story short she got 5 dollars, and she refused to do it. She went to another preparer and 4 days later, she came back to finish it with me. I said to her: I really prefer you try to do it somewhere else. 

My question:  Do I have the right to refuse doing the return for her? 

Note: I did not charge anything the first time.
