Yes and No. This is a product based opportunity and the way you make money is through the sales of product. However, there is no personal selling, telling or explaining that you have to personally do because the system does it for you.
I've been to about 6 weddings in the past year, and none of them actually did the bouquet toss. I thought it was a nice classy touch to each wedding. I really can't stand the bouquet and garter toss, so it's been nice to see a bit more class added back in to the ceremony.
Because it proves the bride's worthiness. Why do we ask our flower girls to toss flower petals? It guarantees the couple many chances to have kids. Why do we go on honeymoons? It is considered a cooling-off period for the bride's family (what a surprising meaning!) Why do we decorate wedding vehicles with cans? The noise frightens away evil spirits.
