In Japan, signs of "with materials" and "without materials" abound, such as "with materials parking lot" (paid parking lot), "with materials road", "without materials to show", "without materials in the box" (free inquiry office) and "without materials observation platform".
This is incredible in Japan where the tradition of "men are superior to women" is deeply rooted! Later, after explanation, I suddenly realized that "material" here is "material money" and "no material" is free. "Men don't expect" not only welcomes men to enter, but also gives them preferential treatment. Knowing the meaning of "not expected" and "expected" is easy to understand, that is, charging.
Extended data:
Accident cases refer to common sex service institutions in Japan. Don't think what you do in an emergency is really free! The accident case is only a purely introductory place and does not provide sexual services.
The staff in the institute is equivalent to China's "pimp". They will contact several nightclubs in advance to make a profit by introducing specific nightclubs to their guests. Therefore, the unexpected situation is not really free for you to enjoy, but really free first and then charge.
