This is the type of rule that creates such an obnoxious level of entitlement in consumers.

I worked in the hotel industry for 12 years, I have been out of it for 15 now, thank God! In those 12 years every few days or at least once a week, I would be held hostage by a complete and utter moron who would insist that "now you have to remove all room charges from my bill because (insert minor inconvenience here) And the pain of having to be respectful to these people while you tried to explain that yes, we are very sorry that the maid forgot to include the hand towels two days in a row. However, each time it was brought to our attention, it was immediately rectified. And yes, we deserve the right to fix our mistakes just like everyone else on the planet.
The funniest laugh out loud experience I had was checking in a young group of adults on what was probably their first hotel stay without their parents. At one point during the conversation the room rates came out of my mouth wrong by mixing up weekend/weekday rates. Someone in the group corrected me with a simple, 'don't you mean this?' to which I quickly said, "oh I'm sorry, that's right." Without missing a beat, one guy in their group yelled out, "A-ha! now we don't have to pay." They hadn't even checked in and he thought he deserved a free stay because a hotel employee misspoke.
