Lockers create love hotel loyalty

According to Joi Ito, Japanese love-hotels have lowered churn and increased customer loyalty by adding storage lockers, because:
Married couples found it convenient to store adult toys and other things that they didn't want their children to find in these lockers. These lockers created a relationship between the customer and the hotel and dramatically increased customer retention. Now these lockers are used to store all sorts of "Not Safe For Home" things.
