Cayla Chandara says she's heard of other stories like this, but never thought it would happen to her. When it did, it left her speechless.

Cayla has been pulling double duty as a waitress at the cheesecake factory and Noi Thai Cuisine in Waikiki.

She was waiting on a couple of visitors from Australia at Noi Thai, and says they hit it off. The three of them ended up chatting with them quite a bit.

"They asked me where I was from and I told them I moved here for school but I was kinda in a little bit of debt and I couldn't go back to school because I couldn't afford it and the cost of living here," Cayla explained.

After a good meal and even better conversation, the man and woman paid their $200 tab and left.

Cayla was shocked to see they left a tip for four hundred dollars.
