I was looking at my mastercard statement to find a couple of charges I made to get to LA and I found a late fee. I panicked for a second, and realized that it was a $19 late fee on residual finance charges leftover from when I *thought* I'd paid off my credit card. But the payoff online didn't account for the five or so days it took for everything to go through. So then they charged me the residual finance charges, and then a late fee for not paying it off on time. And I called them and they took care of it.
I feel very responsible for not just paying them another 19 out of pocket on their mistake.
I am very tired, but wide awake from the coffee I drank to stay awake at the end of my shift. So now I'm doing finances waiting for caffeine buzz to end.
