864 yen!?If the overdue charge was lower than repeat rental charge...In other words, by having a high overdue charge, it serves as an incentive for people to return their items on time.That's higher than when I first rented them!People would think "One or two days late won't hurt anyone."Why is it so high!?That's just weird!Yeah...Makes sense...It's how it is.Yeah, but still...Ah...I can't tell you the exact reason, because it's not me who decided the price of these items.But, if the overdue charge was low, I guess more people would return their items late.
