People who want free advice

A positive contact is always better than a negative contact, as they say in marketing a contact with a good experience will tell five people but a contact with a negative experience will tell nine people.

You are right that you have no obligation to provide free advice, but once you have made that statement to them and offered to make an appointment to discuss services you can provide ask them for their email address so you can send them a link to your website or the IRS site where they can find answers to many of their questions.

I hope this helps,
