Beer hall causes controversy by banning Korean men in their 50s and 60s from entering = South Korea

A notice was posted at a beer hall prohibiting Korean middle-aged men in their 50s and 60s or older from entering.
The information is a hot topic. According to A, who wrote to X, this beer hall is famous for taking requests for metal and rock music from customers and playing those songs.
It is a beer hall with a unique concept where requests for pop songs are prohibited. Mr. A said, "The owner is a very nice person. He loves heavy metal. However, some middle-aged men once came to the bar and started playing heavy metal.
"I asked him to play a song by the popular singer Lim Young Woong, and we got into an argument," he said. Another netizen then said, "There are a lot of middle-aged Koreans in their 50s and 60s who come to the store.
"There is a sign saying 'No men allowed', but was it written because of that incident?" I asked. Then, another netizen shared a long notice posted at the entrance of the beer hall.
The notice reads, "Korean middle-aged men in their 50s and 60s or older are prohibited from entering the establishment," and adds, "Following inappropriate language, abusive language, singing loudly, smoking indoors without permission, running errands for cigarettes, damaging property, making terrorist threats, etc. are prohibited."
"I have suffered great mental distress over the past two years due to his persistent and unreasonable behavior, and therefore I am strictly forbidden from entering the facility. I truly cannot enter the facility. We ask for your understanding," the statement read.
Netizens who saw this commented, "I wonder how much trouble this has caused," "This is no ah-joshi (old man) zone," "As a self-employed person, I play Lim Young Woong's songs at Rock Cafe," and "
"It's cute that he wants to do it. He doesn't even belong in the monster category," "I'm in my 50s too, but I can understand how the shop owner feels," and other comments were posted.
