The availability of these services has made illegal, exploitative loan sharks rarer, but these legal lenders have also been accused of behaving in an exploitative manner. For example, payday loan operations have come under fire for charging inflated "service charges" for their services of cashing a "payday advance", effectively a short-term (no more than one or two weeks) loan for which charges may run 3–5% of the principal amount. By claiming to be charging for the "service" of cashing a paycheck, instead of merely charging interest for a short-term loan, laws that strictly regulate moneylending costs can be effectively bypassed.
