While Terry is trying his hardest to satisfy his employer s demands, and putting his own life at risk, Arthur is busy exploiting Terry for all he is worth. For, when other people hire Terry s services, through Arthur, Arthur usually keeps most of Terry s share of the money for himself, by misleading the hard-working Terry as to the amount of money, he (as Terry s agent) is receiving on Terry s behalf.
