And more on the subject of duvet covers.
If a hotel doesn’t offer a duvet cover and expects you to cover yourself with a blanket that’s lying on top of a sheet, remember: this is a lousy hotel and you have been stiffed.
Just think about it: there is no likelihood that duvets are dry cleaned after each visitor, right? This duvet (separated from a person’s body only by a sheet that obviously shifted a lot as the person slept) touched all kinds of body parts and absorbed all kinds of bodily fluids. Is it very respectful on the hotel’s part to ask you to put that on top of yourself?
