My Hotel Ethics »
Generally speaking, I probably use most of the consumables found in the hotel room - the soap and the shampoo being the two most notable examples of this. There are certainly times where I'll stay for more than just a day, so I'll end up with an extra shampoo or even some bars of soap. As I travel a decent amount, I will typically take some of these with me, in case I run into a place that doesn't supply such things.
If the lodging is more personal, such as a Bed & Breakfast, then often the toiletries will be supplied in a standard consumer-grade bottle, which is naturally much larger, and probably not supplied just so you can take it home and not have to buy your own. On the other hand are other facilities which don't supply anything - in this case those extra "trial size" toiletries come in handy.
