I work for a national Bank that picks and chooses who and when to charge NSF fees. They will almost always reund the NSF fee to a select group of people, It is one customer that is very wealthy and forgets to deposit or some other excuse, ends up with several NSF fees, the bank refunds those, but Joe Blow comes in with five bucks they charge him as much as possible. Is this legal? I feel it is morally wrong.
