It's sleazy, black-hat marketing. They count on you to pay it rather than kick up a fuss. Often, they will remove the charge if you persist in objecting after they make one attempt to 'explain' it to you (they try that much because some people will, however willingly or grudgingly, come around with an attempt at explanation). It's like that catch on FreeCreditReport.com and similar sites that you don't notice in the fine print, that signs you up in some sort of 'savings club' having a very unclear, if any, purpose, at a $3.00 monthly charge on your credit card bill: a lot of people let it slide, at least for a few months, rather than call them up, wait on hold for twenty minutes, and demand to cancel the 'enrollment'.

One of my own pet peeves in that area is that dollar per night extra charge that gets tacked on to your bill for 'insurance' on the contents of your in-room safe, whether you use the safe or not. Most people don't notice it. Even the contract with the safe supplier provides that the hotel is supposed to take it off if someone complains about it. There may even be a case where an in-room safe was broken into, someone made a claim on that insurance, and the insurance paid off the claim, but I'm not aware of any.
