Recently I use some discount or free coupons almost every time I order in coffee shops. However, I think it might be heavy that I have to spend my own tension and time costs for managing them, for example keep presenting a bar code to the shops for earning points.
A foreign woman got on the bus, then showing something on her smartphone and asked the driver whether to go the place. However, the old driver complained in Japanese the smartphone letters were too small to read for him. She didn't understand what he said and repeated the same question.
In the neighborhood, A foreign man asked me where the “Samurai Museum” was. I didn't know such one, and I couldn't find it on my smartphone. So I said there was no such spot near there. However, I realized later it might be a treasure museum at nearby Honno-ji Temple.
I used QR code payment many times, but I couldn't read the QR code at that time. I asked the shopkeeper why, but she said everyone except you use it properly so didn't know why. So I couldn't help paying with cash. She laughed scornfully as if I were stupid.
