“A regular customer is so sensitive”: Restaurant owner blames customer after serving mackerel grilled to a cinder [What do you think?]

[Financial News] A story about a customer who complained after being served grilled mackerel blackened at their regular restaurant, only to be told they were “too sensitive,” has sparked outrage.
On the 9th, a post titled “Charcoal-Grilled Mackerel (Apparently I’m Too Sensitive)” appeared on the online community Bobaedream.
The poster, identified as A, shared a photo, saying, “The grilled mackerel came out much later than the pork stir-fry, just as I was nearly finished eating. It smelled burnt, so I turned it over and saw it was practically charcoal.”
The photo showed grilled mackerel with one side burned black as charcoal.
When A complained, the restaurant reportedly said, instead of apologizing, “Were you going to eat it all anyway? Couldn’t you just pick off the flesh and eat that?”
When A showed displeasure, the restaurant took away the burnt mackerel, but remarks could reportedly be heard from the kitchen, including “You’re too sensitive,” “Cook it at home,” and “Why eat out if you can’t even understand this?”
A complained, “The owner came back and said they’d grill another mackerel for us and we could eat before leaving, but also said there would absolutely be no refund. They said, ‘This isn’t a hotel. What more do you expect?’ They also said the charcoal-black mackerel had been served to other customers, who hadn’t said anything, and that we were the only ones being sensitive.”
A continued, “I checked with an employee who was there at the time, and they said the owner knew the mackerel was burnt but sent it out to the customer’s table anyway. When I asked why, the owner actually raised their voice, saying, ‘You’re a regular and you come here often. Can’t you understand that? Didn’t we even give you toasted-rice tea and a bowl of rice for free?’ I’m so angry, wondering how much they must have looked down on us to respond that way.”
People online who read the account responded, “The owner should have admitted fault and apologized right away,” “If you served that at home, your family would curse you out,” “Instead of treating a regular well, they saw them as a sucker,” “How could they serve that to a customer?” and “I guess they don’t want to be in business.”
