Califonia woman left frightened after Pizza delivery man sends four-page threat for failing to tip him

A Californian woman was left frightened after getting a "scary" letter from a disgruntled pizza delivery man who she failed to tip.
Lauren Olivia Ledford from Redondo Beach in California used Postmates, an Uber Eats-type app, to order pizza and says she assumed the US$4 tip was included in the fee.
A week later she found four pages letter on her doorstep, allegedly from the pizza delivery man, telling her to "not be cheap" and "joking" that he would rob her.
"If it turns out that delivery driver is me again, and you do not tip yet again, I'm probably going to rob you. I'm joking, but not really," the letter said.
"Who knows what a disgruntled delivery guy who can't afford to eat that day is capable of," The letter continued.
The letter left Ms. Ledford terrified that she took to her social media account share snippets from the four-page message.
