“That’s not customer service, that’s exploitationâ€
Even smaller banks can rake in tens of millions of dollars each year through overdraft fees. That's pure revenue, and they have no interest (pardon the pun) in walking away from it.
Publically, they'll tell you they hate overdraft fees and only charge them to "teach the customer a lesson." Privately, they relish such fees, and *really* relish the customers who habitually overdraw their accounts.
OTOH, it's not a complicated arrangement, and it's the customer who puts him or herself into a situation where overdraft fees are charged.
