Whether watermelon is rotten or not, only those who eat it will know

Hello everyone, I will share an interesting thing with you. The thing is like this last time I went to the factory entrance and passed by where the fruit stall was selling. I bought some apples and was about to go back to the factory. At this moment, a big brother just next to him bought some fruits and watermelon and paid and left. I took a piece of watermelon and ate a bite and ran back to the boss and said: Why is this watermelon so rotten that you can’t eat it? The boss said it’s impossible. Then the big brother took another piece to the boss, and the boss took a bite and said there was no rottenness , The eldest brother said like the boss is angry, you have to be conscientious when you sell things. If you are obviously rotten and you say no, the boss said that there is no rancid. , One said no, and later one of the elder brothers said that I gave it to you and left angrily. After the eldest brother left, the boss murmured and said, "Can you blame me for your own choice?" I saw where the watermelon was cut up and sold. Whether it is rotten or not, only the two of them know best? Do you think it is rotten?
