Robotic Server

　　Ozu city is located in the south of my hometown, whose population is only 40,000. I was working in the city until 6 years ago and I was invited to join a party there.
　　The party was held in a small izakaya, Japanese style bar, in downtown. Sitting at the table, a waitress handed us a slip with a QR code printed on it. Scanning the QR code, the menu appeared on the screen and we had only to tap on the pictures of dishes to order. The bill was automatically calculated and we were able to check it anytime. I understood that this method would save the modification and printing costs of the menu.
　　And one more thing, some of our orders were served by a robot. If I were in Tokyo or big cities, this could be, but I was in a small rural city. I wondered if it was due to the lack of workers.
