It really isn't going that far to note the mini-bar stocks only cans of soda so I bring back larger 500ml bottles, which are usually a better value anyway. Also as Sharon has noted there are some occasions where simply saying I didn't use the mini-bar and am not paying isn't always enough so any small thing I can do to avoid these false charge I generally try to do it. Despite this however I have still had these charges appear on my bill and had to dispute them either at check out or during my stay if I noticed them on the room folio accessed through the TV.

I guess while we're all different in our approaches (I've never unplugged a mini-bar fridge for example) the recurring theme seems to be that these charges have happened to us all at one time or another. Call me a skeptic but I still can't accept it's entirely some innocent oversight that sees these amounts appear on room bills.
