Meng Chang was the one who arranged for the ratings of the cold noodles to be placed in the second last segment with a selfish intent.
The only reason Meng Chang organized this Street Food Contest was to market Cold-Faced Lady.
Putting the ratings of the cold noodles at the back would leave a deeper impression on the audience. However, it would not be appropriate to place it at the end. That would be too obvious.
Putting it in the second-to-last order with the last to appear as rare local snacks. That would ensure that the audience would not be too disgusted and would have a deep impression of the cold-faced lady. At the same time, the judges would brag about the cold-faced lady's roasted noodles. Compared to other cold noodles, it would strengthen the impression that the cold-faced lady's roasted cold noodles had the best taste.
That was all tricks.
