These are used as in you've just used them in your room and not a collection of half empty bottles and bars of soap for sale at reception.

Personally I wouldn't take anything like large bottles. If I liked the stuff that much then I'd want a new bottle that I knew would be full.

Apart from the extra line before 'Final invoice' and Inter Continental' as two separate words I see nothing wrong with the sign.

At the San Francisco IC the other week there were signs on the bathrobes saying if you took them you would be charged for it. But again if I wanted a bath robe I'd want a brand new one.
