Carlotta Flores, who owns a Mexican restaurant in Tucson, Arizona, said her son called her one night last week to tell her that she had to come by to pick up an envelope, and that she'd be greatly surprised.
Inside was a handwritten letter from someone who said she used to work at the restaurant, El Charro Cafe, in the 1990s ... and $1000 cash, according to local reports and photos shared on social media.
The person, who did not leave a name, said that while she was working as a waitress and studying at the University of Arizona, she had stolen a few hundred dollars from the restaurant. Now she was trying to make it right.
"One of the waiters I worked with had encouraged me to 'forget' to ring in a few drinks a shift and pocket the cash. And for some stupid reason, I did it," wrote the person, who signed the letter, "A thankful former employee."
"I hadn't stolen a dime before then, nor have I since. Thankfully, I was a terrible waitress and you all fired me before it could amount to more than a few hundred dollars total. It's been 20 years, but I still carry great remorse. I am very sorry that I stole from you. Please accept my apology + this money as a repayment + 20 years of interest."
