Non Stop KY?

This morning we got a railway trouble in Tokyo. I had to wait about 30 minutes for recovery around the station and saw the above drop curtains.

In Japan, for these two or three years, we often use a phrase Ku-Ki Yomenai (空気読めない) (Wikipedia entry in Japanese) which roughly means "Spoiling the atmosphere" to describe such a person. Maybe that reflects tendency of Japanese people placing greater value in cooperativeness than individuality. But, it's not the point today.

As it's well known, we Japanese love making everything short, small and light.
So, "Ku-ki Yomenai" is often reffered as an abbreviation, KY.

Here, I guess you understand what I felt looking at the light blue drop curtain with a huge "KY" this morning. :o

Well, the above "KY" stands for "Kakaku Yasuku" (Cheap Price), but I'm wondering that the advertising strategy is almost a gamble...
