Not a fuck was given that day (ch 45)

Something I just picked on.

At the start of the series, Ruri's class and subsequently school was sent into shock by her change. Even her in the ball teacher couldn't help but get a feel of her horns. I don't recall much of the outside world reaction, however, in this chapter, they get into a country trip and no one reacts to the horned girl at all. No personnel, no passengers, nor the cabbie (mom mentioned dragons within his hearing distance)

Seems quite weird, considering the kids original reaction. Are dragons more commonly known in this world that has been let on, or do the people of the world just dgaf?
