Willie Sutton's maxim is turned on its head in Belgium:
BRUSSELS — To combat the growing problem of 'tiger kidnappings', ING banks in the area around Liège will not hold any cash starting from Monday morning.
....It means there will be no cash held on the premises of Liège banks on Monday mornings. However, cash will reappear in the hours after opening.
....A tiger kidnapping involves robbers forcing entry to an employee's house, kidnapping them and forcing them to drive to their workplace to open a safe.
