I do, many times. The UK 1 carry on rule plus combination of cold snowy climes and hot tropics in the same trip was a challenge, until I realised I could exclude the coat and anything in the coat pockets, plus the liquid baggy, from the 1 carry on.

Then again I don't carry food with me (unless I have a special request delivery) and I've only dropped off one book plus a few magazines along the way (so far).
