Receipt posted by Tumblr user (photo: casualcynic.tumbr.com)

A waitress and Tumblr user who goes by the handle "Casual Cynic" posted a photo of a receipt that made her mom's day.

A mysterious customer recently gave Casual Cynic's mother, also a waitress, a $1,000 tip on a $60.42 meal.

Next to the tip, the uber-generous customer wrote, "Your ticket to Italy. Enjoy!!"

On her Tumblr blog, Casual Cynic explained that her mom had been chatting with the customer about her desire to see Italy and how her ancestors come from Florence.

From casualcynic.tumblr.com:

SHE’S [her mother] GOT 8 YEARS OF ART EDUCATION AND SHE’S WORKING A WAITRESS JOB. IT’S PRETTY… SAD AND DISAPPOINTING, I GUESS. HER AND MY FATHER DIVORCED 6 YEARS AGO AND SHE HASN’T HAD A REAL JOB EVER. JUST BEEN STUCK IN A SMALL TOWN SHE’S NOT FROM. THIS MAN WHO WE HAVE NEVER SEEN BEFORE TIPPED HER 1,000 DOLLARS FOR A TRIP TO ITALY. WALKED OUT, NOT ANOTHER WORD. …YOU KNOW. JUST WHEN I START TO LOSE FAITH IN HUMANITY…. HM

The post drew more than 100,000 notes on Tumblr. And yes, Casual Cynic is aware of the $0.42 addition error on the receipt. In a quick update to her blog, she wrote, "We know about the 42 cents, lol… We have it covered."

The Upbeat was unable to confirm that the receipt is 100 percent legit, but we're choosing to not be casually cynical about it. Because, after all, these things do happen. Last year, we posted a story about a man whose last wish was to have his brother leave a waitress a large tip. After raising money online, the surviving brother now travels around the country, leaving big tips to people who don't expect it.
