DarkStar_ is right. You can charge as much as you want but you should inform the borrower before sending anything and not after.
Probably just a pre-pasted message, just my speculation.
He change though the amounts to the proper ones and update the spreadsheet...
Since it's a loan without any specified interest, since mday failed to agree any interest beforehand Jacee could pay back the 0.01BTC only or any with any amount of interest. I think the 0.002BTC was a suggestion (although mday could probably do with a wallet boost anyway).
Or just pay the transaction fees.
