Another (smaller) example. Most (all?) states have laws capping the amount a bank can charge for an overdraft. But, if the bank the check is drawn on pays it instead of bouncing it, they can charge the account owner a "convenience fee" for covering the overdraft.
This is the same dodge they use with credit cards. Charges are, for the most part, never refused regardless of whether there is any credit left. They will just authorize the transaction and tack on some extra fees.

To show how damaging it can be for someone trapped in a cycle of late fees and penalty rates, CA calculated approximately how much it would cost a hypothetical cardholder who carried a $2,000 balance, paid only the 2% minimum payment and did not meet the due date three times in six months.or [link|http://www.reporternews.com/biz/cards1107.html|here]:
The cardholder's payments were not on time in the second and third billing cycles, which led to two late fees ($25 each) and an increase in the cardholder's interest rate from 13% to 24%. In the sixth billing cycle, the cardholder paid late again, incurring another $25 late fee. By the end of six months, the cardholder's $2,000 balance had increased by $76 and he had paid $277 in interest and late fees.
"This study is the first to reveal that in the last two years banks have imposed penalty rates and significantly increased fees," said Stephen Brobeck, executive director of the Consumer Federation of America, a Washington-based association of more than 260 pro-consumer groups. "Essentially what's happening is the issuers are shifting costs onto the most troubled debtors: those who have trouble making payments on time or may exceed the credit limit."
