I’m happy NOT to have a minibar for just this reason. I have been charged on rare occasions, in hotel rooms or on cruises, for things consumed by a previous guest. I have tried to take inventory myself upon arrival, but the list provided doesn’t always match what’s stocked in the minibar. It may be outdated OR some items might be temporarily unavailable and therefore missing. So you don’t know for sure if it’s FULLY stocked unless they check it. That’s why I actually welcome a staff person who comes to my door to check. Not because I’m going to use the minibar - I NEVER do - but because I’m confident it’s been officially checked. It especially irks me when I am charged POST checkout for an item I did not use. It takes time to call the hotel & get someone to remove and credit me for a $5 or $10 erroneous charge, and then I have to check my credit card bill. I bet many people do NOT notice or follow up on this type of error. But I do!
