Source for Inspiration

We went to the school canteen to order some drinks. When we paid her, we saw that all the coins were spread out messily on the counter and its hard for her to find the right coin.

Source for Inspiration

Another time was when we were on a taxi, and when we reached our destination and were paying the taxi driver, we realised that he had a lot of problem getting the right coin in the box full of coins.
