A public speaking friend of mine had a deal with a local flower shop. When he had a program he would buy up all the fresh flowers that the flower shop could not sell. He got them for a really cheap price. The flowers were destined for the dumpster anyway so the florist was thrilled to get anything for them.
The speaker would arrive to big fanfare 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 the people in the audience had a blast.
