A restaurant owner in Arizona received a surprising delivery last week: A handwritten letter from a former waitress, along with $1,000 cash.

The anonymous former employee says she was a waitress at El Charro restaurant, owned by Carlotta Flores and her family, “very briefly” back in the 1990s while she was a student at the University of Arizona.

She explains that while she was working, one of the other waiters encouraged her to “forget” to ring in a few drinks during her shifts and pocket the cash.

“For some stupid reason, I did it,” the woman wrote. “I grew up in the church, I knew better. I hadn’t stolen a dime before then, nor have I since.”

The woman goes on to say she was a terrible waitress and was fired before the money she took amounted to more than a few hundred dollars.

“It’s been 20 years, but I still carry great remorse,” she said in the letter. “I am very sorry.”

The former waitress explains that the money she sent along with the letter is her repayment, plus 20 years of interest.

“May God forever bless you and your family,” she wrote, signing the letter from “a thankful former employee.”

Carlotta Flores’ son, Ray, posted a picture of the letter and some of the money on Facebook over the weekend. Hundreds of people have liked, commented and shared the post.

“You don’t always have to tell someone who you are to make things right for you both. This made our week!” the post reads.

In a separate post, Flores shared that his mother had been robbed while grocery shopping two days before they received the money. 

“She had been very down over that experience and then this kind act occurred,” he said, calling the whole situation “the roller coaster of humanity on full display.”
