The same at certain hotels where a %high of bathrobes seem to make it by their own out of the room and seem to check outof this planet...
It usually say something like:
- please enjoy them for your comfort during our stay,
if you are interested in after stay comfort, please know these are for purchase....


in a personal anecdote:
on certain Lufthansa and Swiss First flights
in the lavatory one may find La Praeri Handcream (retails around €80)

flights to a certain country in the northern eastern sphere,
see before landing and securing cabin, both flasks taken,
by women whose faces have been so tightly pulled, it makes Cher look natural!
most likely for home consumption.....


Lufthansa thought to be smart and removed the screw cap,
Because the thought is whom is going to carry a tube that can squirt!

The same with the Business Class lotion/scents in the Singapore Airlines lavatories, all screw caps are removed to reduce % of it being stolen....

About the sign:
So nothing about used toiletries for sale or such !
