"Li Xue, were you really a chef here before?" Shen Bingling still couldn't believe it. But reality couldn't be that twisted when everything was crystal clear on the surface. She has heard how respectfully the manager has come to greet her earlier. From his gesture and tone, it was enough to tell that not just the girl was a chef was also the best in her job. Otherwise, there are so many chefs around, not everyone gets respect wherever they go. 

Li Xue didn't reply to the girl at first. Instead, made the waitress note the name of the dishes first before making her leave. Then turning to look at Shen Bingling, she shook her head to say, "I was just a dessert chef in one of their dessert chains. Nothing too high."
