How often is transportation money actually paid upfront? Has this ever been researched through a survey or anything similar?

Maezawa here with an answer. I don’t believe we’ve ever conducted a survey like that. Also, we have no way of knowing how many people fail to pay in advance—that is, violate the rules. If a woman doesn’t receive the money she is supposed to under the rules, she’ll contact the club, so we can keep track of those cases. However, as long as she receives the money properly, it seems she generally won’t contact us, even if the payment is made after the meal.
