Just before closing time on November 22, a man walked into the Cleveland jazz joint Nighttown. He ordered a beer, asked for the check, and wished the owner Brendan Ring well.

Ring looked down at the credit card slip the man had left with him. When he saw the amount he had left, “I ran after him,” Ring wrote, “and he said no mistake we will see you when you reopen!” 

In a Facebook post, Ring said the man asked that the tip he’d left be shared with the waitstaff.
