Tsai John T CPA doesn’t know how to respect customers when he is not knowable enough to answer your question.
He may just ell you “I DON’T WANT TO TALK WITH YOU” and “STOP!
NOTHING IS WORTH A DISCUSSION HERE” when you are just about stating your case and questions.
He does not appear to be a very knowledgeable CPA.
Generally, even though you are not knowledgeable enough, at least you should know how to respect your customers by understanding their needs and question and tell them ” I am not good in this area, and I am sorry that I couldn’t answer your questions” But he may just tell you “”I DON’T WANT TO TALK WITH YOU” and “STOP!”
In an very arrogant way to (maybe) just to hide the fact that he is not knowledgeable enough to answer your question. I will let you decide!
