Public Speaking Course:
Say it with Flowers
I have a friend who is also a professional public speaker that made a deal with his local flower shop, that helped him make a lasting impression during his presentations. When he had a program coming up he go to the florist and buy all the fresh flowers that hadn't been sold. Because the flowers were destined for the trash anyway, the florist sold them for a really inexpensive price, just being thankful to get any amount for them.
My friend would arrive and create a big fanfare by throwing flowers into the crowd. Everyone got a flower to take home and depending on the size of the crowd, some would get a whole bouquet. He also sent big bunches as his thank you gift to the meeting organizer. He purposely sent so many that the organizer could not possibly take them all home. His good will (and name) was spread all over the company he was speaking for and left a lasting impression on his audience. This is a unique way of showing what you learned in your public speaking course.
