A recent post on Imgur proves there are still good people in this world - and very generous, too.

The waitress, from an undisclosed location, shows a receipt for a $9.53 bill where a patron also included a $200 tip. The heartwarming note on the back of the bill explains the reason for the diner’s generosity.

‘Brandi, thank you for your service. I overheard you talking about your son. Use this to visit him.’

Brandi said in her post, "I completely broke down in the kitchen when the host brought this to show me. Kind and caring people do still exist!"

You can bet she'll pay this forward someday - and that's how it works.
