Slob clients
Did you ever notice that some clients open up their mail, including their tax documents, like Godzilla after he ate a forest of fermented berries. I did a Google search and the letter opener has been around since at least 1850. Maybe that would be a good advertising avenue for tax preparers, they could put their name on letter openers, and maybe that will also remind them to save the documents for tax season.
