In The Character Of Africans - Spraying Money At Ceremonies:

The art of spraying money at occasions gradually became the African culture for several years. But in recently, the traditional character of spraying money on couples or celebrants during ceremonies has seen its demise.
This is due to certain suspicions that arose consequent upon recent occurrences in the continent, some of which are attributed to the art of spraying money.
Now, celebrants do not allow money sprayed on them, they prefer that guests either drop the money on the floor or enclose it in envelopes, all as a form of support to the celebrants.
The art of spraying money is said to have more advantages than  the latter because while many consider the act unhygienic and an abuse on the currencies, there are others who still fancy the idea as they would not want to discourage their guests from participating in the cash-spray.
It is argued that guests tend to give more when they spray money on the celebrants because it is open and clearly seen by everyone. But when the money is to be enclosed in an envelope, anyone can enclose anything less as no one else will know the amount in it. Celebrants always want to make money after spending so much in organizing the occasions, hence, despite the ban of spraying  money in most parts of Africa the practice still goes on.
The video footage below shows a groom and his best man cheered by their guests as they compete in in a dance and as usual, some of their guests spray money, but this time not on them, on the floor, as their own way of showing their support.
