Here are a couple of quotes from the
hotel industry. The highlight is mine. I'm sure there are people for whom staying at the top hotels is an everyday occurrence then there others for whom it is an occasional treat. The linked article also makes clear the toiletries are part of the room cost.
If the free toiletries are what you want, then go wild, said Jacob Tomsky, author of the best-selling Heads in Beds, a memoir of ten years spent in the hotel industry.
“Hotels have plenty of items, all cute and travel-sized, waiting in store rooms and all you have to do is pick up the phone and ask. And checking out from the hotel isn't like going through airport security. No respectable hotelier is going to want to pry open your luggage and search for shampoo. We hope you take the amenities. We want you to use them later and think of us."
"Hotel rooms often also include branded material like pens, pencils, notepads, postcards, and the like. These can be considered as marketing material. Every time you use the hotel's pen, for example, you will indirectly be advertising the brand. It is probably safe to assume that the hotel management will be OK with you taking such items with you when you leave".
