On Nguyen Trai Street, Kon Tum city, there is a small, squat pub. Japanese-style doors often hang a small, two-sided wooden sign "There are guests" and "Please come in for a drink." Attached to the wall is a wooden sign with four words: "One person pub". It's understandable, the restaurant is only open to one customer at a time, so customers can eat and drink freely. There were also many people who didn't know how to open the door and were immediately invited out by the shop owner and guests who were drinking. Some people get upset, some people curse, others leave. But once they drink at the bar, customers immediately pocket the address of their favorite bar. Perhaps partly because the wine is good and the food is suitable, partly because they like to talk to the shop owner.
