Collecting my fees

I have great difficulties in collecting my fees. The Economist writes that Japanese loan sharkers call a borrower's workplace a dozen times in an hour demanding repayment. Or send debt collectors to his home in the middle of the night. If the fellow said he could not pay, the representative recommends he sell a kidney or an eye to raise the cash (and offer to remove it for him). The yakuza, the tattooed mobsters, are in the background. The problem is that my clients would laugh off those illustrated gentlemen. My people are hardened Levantine low life "businessmen", they dont understand why they should pay me if they can evade the pain, they have no sense of Jewish or otherwise guilt, they had never met anyone with a sense of shame. Unlike those nice, polite, decent Japanese.
