  # Ensures Charge has always positive amount.

  # Amount should be modified ONLY when it's going to be saved to the database
  # (read_attribute returns value)

  # WARNING! It does not protect from Credits getting negative amounts while
  # amount is autocalculated! Descending classes should ensure amount is always
  # negative in their calculate_adjustment methods.
  # This method should be threated as a last resort for keeping integrity of adjustments
