So the top management of the company decided to have a brain storming session to find a solution to the cup problem. The person moderating the session explained the rules of the brain storming.
Next day when a smaller group sat down to evaluate the ideas based on particularly, cost etc, they said"
Why not? Why don't we serve ice cream in cups which the customers can eat with ice cream?"
And the Cone ice cream was born. Now the company makes profit on the ice cream and on the cups.
