At least Hollywood Video is marginally better about the whole late fee thing than Blockbuster. At Hollywood Video, when you fail to return your movies on time, they rerent them to you for another full rental period. When you fail to return movies on time Blockbuster, they charge you for another rental. Every day. I recall reading an article once saying that some astronomical percentage (I think it was around 60%) of Blockbuster's income came from late fees. It wouldn't surprise me in the least.
So anyway, I need to stop doing that. (She says, while staring at the stack of four movies, unwatched, that were due back at midnight tonight. *sigh)
