Kang Yu-mi turns "cigarette" coffee complaints into a cafe roast
Kang Yu-mi slips into a barista persona on SNS, taking aim at rude cafe customers over cigarette-smelling coffee and free refill demands.
"The burnt smell is due to the bean characteristics" A logical rebuttal
Comedian Kang Yu-mi has transformed into a cafe owner, delivering unrestrained "snipes" at customers who cross the line.

Recently, Kang Yu-mi posted photos on her SNS showing her dressed as a barista standing in front of an espresso machine. In the photos, she holds coffee beans with a dissatisfied expression, providing an immersive sense of being an actual cafe operator.
In the post, Kang Yu-mi opened with, "Another nightmare customer appeared today. They said the coffee smells like cigarettes or something."
She then offered a logical rebuttal to the complaining customer, writing, "Our cafe uses dark roasted beans. Due to the nature of the beans, a burnt smell can occur."
She also followed up with remarks poking fun at the customers' discernment. She wrote, "Coffee culture has advanced so much in our country that there are many great cafes handling various types of beans. However, it is a shame that customers' tastes still seem stuck on low-cost coffee."
"Yes, I'm talking about you" Directly targeting customers demanding free refills
She also induced laughter by pointing out a customer who exhibited specific behavior. Kang Yu-mi directly targeted a customer who had requested a free refill, stating, "To the customer who asked for a free coffee refill today. If you happen to be watching this... yes, I am talking about you."
Netizens reacted immediately to Kang Yu-mi's persona acting. They joined in the roleplay with witty comments such as, "Are you writing about me right now?", "I am a 52-year-old female head of household who worked part-time here for 40 years.", "This unnie brought something infuriating again," and "Is this fiction or non-fiction?"
