Waitress CeCe Bruce wasn't having the best of Wednesdays working the morning shift at an Indianapolis Steak 'n Shake.

"I was having a hard time at another table, but kept smiling and going on," she told WTHR.

Her mood ring changed colors quickly, however, when she went back to check on another customer and found that she had been left a $446 tip on a $5.97 bill.

That generous tipper, a regular identified only as "Miss Jo," didn't bother offering Bruce an explanation, but was very insistent that she accept the money nonetheless.

"I said 'Oh my gosh Miss Jo, I'm not taking that!'" Bruce recalled. "And she said, 'Yes, you're taking it' and I said no and she said 'You need to take it.'"

Explanation or no, the restaurant's general manager Greer Gooley is certain Bruce deserves it.

"She stays late, comes in early. Whenever we need her, she's here," Gooley told WISH-TV. "It just lets servers know that you work hard and it does pay off. There are people out there that [if] you do your job people reward you for it."

A part-time student at Martin University, Bruce says she has plenty of bills of her own that need paying, and she intends to do just that with her windfall.
