What about:

1. taking home the cute little glass condiment jars provided with room service such as jam, ketchup, mustard, etc? I am speaking of where you did not have occasion to use them at your actual meal but take home the unopened bottle. Should it be treated like a condiment in those little disposable package, or like full size condiments (which clearly belong to the hotel/restaurant) since they're in cute little only-a-couple-of-servings jars?

And...if that's ok, what about swiping the unused condiment jars from other people's room service trays that they've left outside their room for the hotel to collect?

Finally, what about taking home more disposables (soaps, pillow mints, etc) than just found in your room- say from the maid's cart in the hallway?
