Many guests bring home pens, notepads, coffee bags, popcorn, teabags, and single-use toiletry bottles. Some even bring home toilet paper and tissues.

If someone chooses to forego use of hair conditioner, there is nothing wrong with taking home a reasonable amount (that could have been taken used by a spouse or child during that stay).

However, if too many guests begin draining an excessive amount, this could provide an economic incentive to return to single-use toiletry bottles.
