From a wonderful book by Robert Fulghum. The book is titled "Maybe (Maybe Not)"
On a hot summer's day, late in August, I sought shade and a cool drink under the canvas awning of a waterfront cafe in the old harbor of the town of Chania, on the Greek island of Crete. More than 100 degrees in still air. Crowded. Tempers of both the tourists and waiters had risen to meet the circumstances, creating a tensely quarrelsome environment.
At the table next to mine sat an attractive young couple. Well dressed in summer fashions of rumpled linen and fine leather sandals. The man: stocky, olive-complexioned, black hair, and mustache. The woman: lanky, fair, blond. Waiting for service, they held hands, whispered affections, kissed, giggled, and laughed.
Suddenly, they stood, picked up their metal table, and, carrying it with them, stepped together off the edge of the quay to place the table in the shallow water of the harbor. The man waded back for two chairs. He gallantly seated his lady in the waist-high water and sat down himself.
The onlookers laughed, applauded, and cheered.
A sour-faced waiter appeared. He paused for the briefest moment. Raised his eyebrows. Picked up a table cloth, napkins and silverware. Waded into the water to set the table and take their order. Waded back ashore to the ongoing cheers and applause of the rest of his customers. Minutes later he returned with a tray carrying a bucket of iced champagne and two glasses. Without pausing, he waded once more into the water to serve the champagne. The couple toasted each other, the waiter, and the crowd. And the crowd replied by cheering and throwing flowers from the table decorations.
Three other tables joined in to have lunch in the sea.
The atmosphere shifted from frustration to festival.
One does not wade into the water in one's best summer outfit. Why not?
Customers are not served in the sea. Why not?
Sometimes one should consider crossing the line of convention.
