As an investment counsellor, you made a presentation to the board of directors of Slate Industries at their head office. To assist with the presentation, you provided each of the attendees $($people in attendance$)$ with a brochure explaining your services and providing some information about certain potential investments. One of the attendees left his brochure behind at the end of the presentation and it was subsequently picked up by the cleaner, Barney Rubble. Barney read your brochure and invested his life savings in some of the investments that you discussed in the brochure. Other than collecting all the brochures at the end of the presentation, is there anything that you should have done to prevent Barney from successfully suing you for his loss?
