Stop in for a cup of coffee

Wow... I'm gonna smack my state IRS...

I paid my property taxes for the year in the spring. exactly to the penny specified. They then two months ago sent out another bill, saying they'd screwed up and I owed 2 bucks more. so I paid it. no worries right. Just opened the mail from last night, ANOTHER bill, same mistake in math apparently. Guess what I owe?! .02.... 2 freaking cents. It cost them 46 cents to mail the thing plus man power in packing the envelope. WTF is the sense in that, just tack that 2 cents onto the next years bill. Good Grief.
