"Rounding to the nearest nickel?"

I can guarantee that it will always be rounded up and not down.

But it's only a penny right? Sure but those penny's add up.

Digital "shaving": In the digital age, the idea surfaces as a programmer subtly altering bank transaction code to divert fractions of a cent from many accounts into their own.

Money, it's a crime
Share it fairly, but don't take a slice of my pie
Money, so they say

But if you ask for a rise
It's no surprise that they're giving none away
