Hotelier here. I'll bite.
Toiletries, biscuits and drinks are provided for your use so yes, you can take them. No we don't refill tiny bottles. We provide new.
Taking anything else from the room is theft, and not light hearted or amusing when you are the person paying for it. Margins on rooms are small, hotels are expensive to run. Electricity and heating costs have doubled. Food costs are soaring etc. It's a tough industry right now. The level of theft is upsetting.
Towels and robes are not owned by the hotel, they are provided by a linen service. We have to pay for any shortfall in returns.
Hair dryers regularly used to go missing so we now keep them at reception which is inconvenient for everyone. A shame that we have to but we couldn't fund a new hairdryer every few changeovers.
Artwork is screwed to the walls, antique ornaments are in locked glass cabinets. Again, what a shame we have to do this.
We used to have special branded mugs. We only have a handful left as they were stolen as souvenirs. It's really not ok to steal.
