I remember reading a story about a plainly dressed man who entered a church in the Netherlands and took a seat near the front. A few minutes later a woman walked down the aisle, saw the stranger in the place she always sat, and curtly asked him to leave. He quietly got up and moved to a section reserved for the poor.
When the meeting was over, a friend of the woman asked her if she knew the man she had ordered out of her seat. “No,” she replied. Her friend then informed her, “The man you ordered out of your seat was King Oscar of Sweden! He is here visiting the Queen.”
