”The cost of ingredients alone is 2 million won” - restaurants continue to cancel orders without notice...even sending mocking messages saying ”You're an idiot” - Korea

A self-employed man who runs a Japanese omakase restaurant in South Korea is expressing his frustration at not only being subjected to malicious no-shows (cancellations without notice) from group reservations, but also to ridicule.
According to JTBC's "Case Leader" on May 13, informant A, who runs a omakase restaurant in Bundang-gu, Seongnam-si, Gyeonggi-do, on the morning of the 9th,
At around 10:00 a.m., the restaurant received a reservation order by phone. An elderly-looking man called and said, "I'd like to make a reservation for 28 people at 12:40 p.m. tomorrow." Because it was a large reservation, Mr. A called several times.
He tried to call the number to confirm the reservation, but there was no response. However, Mr. A thought, "An elderly person would never make a prank call," so he prepared additional materials worth 2 million won (about 220,000 yen) and
On the day of the reservation, Mr. A arrived to work two hours earlier than usual and called again, but still could not be reached. However, at 12:13 p.m.
Around 12:00 a.m., I received a call from an unknown number. The caller, a young man, said, "I am calling on your behalf for company business," and after confirming the reservation again, asked me for a high-quality payment of over 1 million won.
Mr. A also requested that he prepare some grade whiskey. Mr. A was unable to prepare the whiskey in time, so he hurriedly prepared only the food, but in the end the guests did not show up.
Mr. A, who was convinced that the person was a no-show, sent messages to the number that had originally made the reservation, such as "I'll remember that" and "See you at the police station."
The replies he received included insults and ridicule, such as "You seem pretty angry," "Live your life to the fullest, you idiot," and "You're an idiot for being fooled by me."
Mr. A said, "In the end, only four people came to the restaurant that day, and all the leftover food had to be thrown away." He added, "Usually we ask for a reservation fee, but I was uncomfortable with that.
"Some customers have had to cancel their reservations," he said. "I even work a second job to pay my staff's salaries, so the damage has been enormous."
Mr. A plans to report the no-show customer to the police.
On the other hand, according to the relevant law, the no-show act was found to be intentional.
In such cases, the offender may be found guilty of "fraudulent obstruction of business" and face up to five years in prison or a fine of up to 15 million won.
