Congratulations to Tony Toastmaster of the day for filling the role of Table Topics Master at short notice.
Table Topics is where you offer the opportunity for members and guests to speak impromptu.
Tony demonstrated care and thought. He set the scene for each of his opportunity related topics before he selected a speaker. What this did was allow everyone including the speaker time to think of at something to begin with were they chosen and as a result those who participated gave well structured and informative short speeches.
If you would like to learn the skill of introducing people in a work setting, meeting or at an event try Toastmasters. Its the place to learn.
