A couple of Australian tourists did something incredibly generous for a young waitress in a Hawaiian restaurant. Cayla Chandara has been working at two Waikiki restaurants. KHON2 reports, she was pulling a shift at Noi Thai Cuisine when a couple from Australia came in for dinner. She engaged them in conversation, and they asked a lot about her. Cayla explained she was trying to work her way through college and pay off some debt. When the couple paid their $205 tab, they added a $400 tip! As you can imagine, she was overwhelmed. Cayla took flowers, and a thank you card to the couple's hotel. They returned the next day with an offer of $10,000 to help pay off Cayla's debt and get her back to school. The offer came with one condition. They wanted to remain anonymous.
