Or let it and allow the person to serve as a tacit example to others.
Paycheck loans, instant cash, instant refund, need money now loans....all have hooks. You see the ads for Geiko, but the very small print blurb they show is really too small to make out on most televisions saying it's a mortgage, and tax preparers who do 'instant refunds' rarely discuss the fees and surcharges before you file with them. 'In between paychecks?' ads never tell you the interest rates, or have them, yet again, in print so small and blurred that it's impossible to read.
As always, caveat emptor.
