Sweet waiting - lollipop / lollipop for the waitings

We all have an experience - waiting in line. It annoys us. Sometimes we stuck in the line and don't know the exact time to arrive. The candies for the waitings give the people who are waiting a "sweet process". There's a number on the package. As the time goes by, the candy will melt away in user's mouth. When the candy vanished, it means you already finished waiting.
