Cafe President Noel (former RAINBOW) attacks troublesome customers on social media: ”I did as requested but I was attacked by a rating terrorism attack”

Noel, a former member of the Korean girl group "RAINBOW," revealed an incident with a customer and caused outrage. Recently, Noel posted on his SNS, "He's really a weirdo until the end. The people who work at the cafe...
Does anyone agree with this?” he wrote in a lengthy comment. According to the photo Noel posted, a netizen gave Noel’s store a rating of 2 points and wrote, “Excluding the ice, there is 500g of ice.
I heard that it will disappear, but if that's the case, they should sell it as 500ml watermelon juice. Isn't it fraudulent to sell it as 1 liter?" he wrote in his review.
He also posted a photo of a half-filled watermelon juice. Noel responded, "The truth is, troublesome customers don't know they are troublesome," and "One liter of watermelon juice is a mess."
They ordered iced drinks without ice, but then they started making a big fuss, asking why the amount was so small and asking for a refund. Why can't they think about the amount of ice?"
"The recipe is decided with all of this in mind. If you don't want the amount to look small, you don't have to ask for the ice to be removed," he said in response to the customer's complaint.
Finally, she said, "I will meet everyone until the cafe opens," and "I will do as you requested."
But all I got was a two-point rating. What did I do? I'm a weirdo who commits review terrorism." Noel opened the cafe in 2023 and has been running it ever since.
In January, he wrote, "The most annoying customer ever appeared at the store." "There were a lot of orders queued up in front of me, so I had to wait a bit. I was wearing a mask, so I thought he wouldn't hear me, so I looked him straight in the eye.
"He immediately started speaking louder, and then he shouted at me with a look on his face as if he was about to hit me, asking me why I was so angry," one self-employed person complained.
