David Fabila was waiting tables at a California wine bar on a hectic Friday evening. He was working the outside patio section all by himself, and guests were pouring in.
David told his coworkers he was having a rough night; he'd just come from his other job and was understandably exhausted.
That's when a younger man sat down in David's section, but David was so busy with his other tables that he didn't get to talk to the young man all that much. When David went to close out the stranger's tab, he saw a note written at the top of the receipt.
"We're young, but we're worth serving," it read.

The bill was $191.35. Then David saw the tip — it matched the total. With the $191.35 tip, the young man had just paid a total of more than $300.
David was left in such a state of disbelief, and was so certain the guest had made a mistake, that he repeatedly checked the numbers on the receipt. "Unless you work in the service industry, you don't really understand how much tips mean to a server, to a bartender," David told CBS.
It just so happens that the guy who left the note and tip was a college student named Steffen Berr. He used to work as a server in a diner, so he felt it right to reward David's hard work. He didn't know David's circumstances, the fact he works two jobs and has three young children.
But there was something else Steffen didn't know about David — something that made the hardworking father all the more grateful to this selfless stranger.
