The following picture shows his checking account balance at the initial splash screen:

See the difference of over $300? That's the bank's "overdraft protection" in action. They're such nice folks that they go ahead and factor that "protection" into the first balance their customers see when they log in. Of course, if the "protection" gets used, a banking fee of some sort is assessed.
Huh.
My checking accounts are held at credit unions, and neither of them do this. Both offer overdraft protection — but both also show my balances as they actually exist. It's this way on every screen.
So is it just me, or is my coworker's bank's practice slightly wormy? Seems like a rather nondescript way of luring naive customers into overdraft usage, if you ask me.
