Customer at kalguksu restaurant pulls out kimchi brought in a side-dish container and eats it... offers unsolicited advice: “You should make your own kimchi, owner” [What Do You Think?]

[Financial News] A story has emerged about a customer who brought kimchi to a kalguksu restaurant and ate it there, then offered the owner unsolicited advice, saying, “You have to make your own kimchi for your business to do well.”
On the 23rd, JTBC’s “Scandal Supervisor” featured the story of A, in their 40s, who runs a kalguksu restaurant.
A began by saying, “Our restaurant is popular by word of mouth, and on weekends we even have a line of people waiting. That day, too, I was frantically serving customers when a woman took a side-dish container out of her shopping bag and ate the kimchi she had brought with her.”
A said, “She may have had personal reasons, and it would have been fine if she had just asked us in advance. But I was taken aback when she ate outside food without saying a word. I tried to bring it up politely when she paid, but her reaction was not what I expected.”
The customer reportedly asked A, “The kalguksu is really delicious, but don’t you make your own kimchi?” A replied, “That’s true, but I’ve tried kimchi from several suppliers and chose Korean-made kimchi that goes best with kalguksu.” The customer then said, “Still, the owner should make the kimchi themselves. That gives the restaurant its own identity and helps the business do well,” A explained.
A said, “I didn’t say anything while she was eating, but it’s difficult when customers bring in outside food to eat.” The customer reportedly replied, “I’m a picky eater, and the kimchi wasn’t to my taste,” then left the restaurant.
A said, “I was already taken aback that she ate outside food without asking first, and then she even gave me unsolicited advice about kimchi. I couldn’t believe it. Some acquaintances I told said, ‘Aren’t customers always right, especially in an economic downturn like this? Just be understanding.’ As the owner, should I just understand and let it go?” A asked for advice.
Lawyer Jihoon Park, who heard the story, said, “There’s no single right answer, but generally people don’t bring outside food to eat at a restaurant, and it’s also rare for restaurants to allow it.”
By contrast, psychology professor Sanghee Park said, “The owner may be upset, but everyone has different tastes and health conditions, so perhaps the owner could try to understand.”
