Last summer, I opened a small cafe jointly with friends. I was able to acquire a small stake by contributing a small amount of money, driven by a desire to learn how a cafe operates. A few years ago, when I was working a regular job, I took over a small cafe and ran a "Saturday Cafe" that was open only on Saturdays. However, I underestimated the difficulty of running a cafe and suffered a heavy defeat. Because I wanted to do better this time, I started buying and reading various books related to starting a cafe business, and this book was one of them.
