The man gave the waitress a $1000 tip. But when she found out who it was, she couldn't believe

It was early morning. Francisca was riding along a picturesque country road on her favorite red bicycle, which her father had given her for her thirteenth birthday. The sun was shining brightly in the sky, but the girl didn't feel hot - a cool breeze pleasantly caressed her face, gently playing with her long wavy hair. Francisca felt lighter and more carefree than ever: all paths were open before her. She stopped by the side of the road, leaned her bicycle against a tree, and took out a blanket, a bundle of sandwiches, and a thermos of cocoa from the basket. Settling down on the grass, Francisca eagerly began to devour her breakfast. Suddenly, the bundle of remaining sandwiches stirred, emitting a dreadful rattling sound. Francisca, horrified, covered her ears with her hands... and woke up.
