The worse sin that a boot slave can commit is to not take proper care of the boots of his Mistress. Joanna has found out that her exquisite Berlin Boots are not properly clean and thus, she promptly demands her boot slave and asks him the reason for this fault.Since he has no excuse, she takes the bullwhip and administer a good whipping to her boot slave. She also teaches him how to properly "clean" the boots of his Owner.
