Yeah...
So I paid my December rent and left a post-dated check for January's rent that they were going to hold (like they did last year). My rental agency deposited both checks at the same time. This resulted in an overdraft from my credit card (what with me being broke and all). I've been dealing with this for a week and the end result is this: The bank didn't charge me an overdraft fee bc I have overdraft protection. The rental agency couldn't get the check returned bc it didn't "bounce." So I'm left paying interest on this amount for one month - until I have money to pay it off. Not a horrible result, but I'm annoyed non-the-less.
It can all be summed up in one word: Hassle.
