I'm not sure which specific 'waistcoat of pancakes' children's story you are referring to. There could be many original or local stories with such a unique name.
Since I'm not familiar with this exact story, I can't say for sure. But it could have a child as a main character, someone who finds or wears the waistcoat of pancakes.
One scary waitress story could be about a waitress working in an old, supposedly haunted diner. She always felt a cold presence in the storage room. One night, while getting supplies, she heard strange whispers and saw a shadowy figure out of the corner of her eye. She ran out of the room and refused to go back in there alone ever again.
There could be many real stories involving a cop, a waitress and a lottery. Maybe a cop frequents a diner where a waitress works, and one day, the waitress wins the lottery. The cop could be a witness to her sudden change of fortune. It might also be a story where the cop helps the waitress when she has some trouble related to the lottery, like if she was scammed after winning.
Waitress is purely fictional. It doesn't draw from any real-life events or people. The story was developed to offer a unique and enjoyable cinematic experience.
There was this waitress, Sofia. In a high - end restaurant, she noticed a young couple on a first date who were a bit nervous. Sofia gave them some advice on the best dishes to share and told them some interesting stories about the restaurant. Her friendly attitude made the couple relax and enjoy their date. They later sent a thank - you note to the restaurant, praising Sofia's great service.
In 'Pulp Fiction', there are various characters and settings. If we consider a broader sense, a waitress could be one of the many types of characters that could potentially be in the movie's universe. Maybe in a Tarantino - like world, a waitress could be a minor character who serves the main characters in a diner or bar, much like some of the incidental characters in 'Pulp Fiction'. But without more specific context, it's hard to define a precise connection.
