I have no idea where you're staying. I regularly see most, if not all, of these items in North American hotels at all levels.

My wife would disagree. While she always makes use of them, I never do so we have dozens upon dozens of unused hotel slippers at home. We offer them to house guests to use and take home.

Count me in. I hate using "body wash" as 50% of it just slips away between my fingers. It's extremely wasteful, and was invented specifically to make you buy lots more soap.
