Hotel Dressing gown n slippers?

hi i have been a hotel house keeper for 4 years you cant take the dressing gown they wash them and use them again if the slippers are the really thin disposable ones you can take them just ask if the slippers are disposable ones oh we do notice if people take things cause we have to report it and damage smoking then they send you a bill not sure why you would want to keep dressing gown any way about a million people have worn it
