The issue of entitlement in lieu of what one paid for the room is moot. For those who claim, "I paid x for this hotel room, so I'm owed that robe" - may I point out that when this game is played by the other party, its weakness is soon exposed. For example, would you accept the hotel's insistence that even at $1000 per night, you are still getting a bargain according to what their rack rates are, and thus they are entitled to ransack your luggage for souvenirs? (They did soooo admire your laptop, say, that they just HAD to have it....)

Bottom line: One contracts for that which one contracts; subsequently upping the ante, and maintaining that an implied contract exists where none did, is rationalization and manipulation of the kind I have usually encountered only with my guilt-tripping mother: In that case, she did not say " I paid X dollars/years to raise you, therefore I am entitled to x, y, or z", rather, her ploy took the form of, "But what are children for?" This was her typical ploy, upon being told, say, that my weekend plans had unfortunately been made some time ago. I maintained that I did not know that because I had been taken to the beach on July 16, 1965, that this bound me to provide x or y on a specific date 40 years later. (Don't get me wrong: I don't begrudge the lady such services as I can provide for her and I enjoy her company, but I do not accept any insistence that when my plans conflict with hers, that this constitutes some kind of contractual default on my part.)

2)The suggestion that anything with a logo on it is a form of advertising and thus meant to be taken raises some interesting implications about all those items marked:

"By Appointment to HRH (Prince of Wales/Duke of Edinburgh/The Queen/Insert Royal name here)"

To the OP: quite possibly you felt disturbed enough by the incident to seek reassurance. Look, I can't justify your taking the robe, but I can maintain, if only as a matter of statistical likelihood (as I don't know you personally) that you are very likely not a felon in the making, etc., just one who seeks to have his logic validated (or not) in a world where the word 'gift' has been misused. (What in heck is 'free gift' as it is used, or rather misused by so many commerical parties today, supposed to mean? Isn't a gift, by definition, free, and isn't its status as a gift supposed to be clear by virtue of the behaviour exhibited by the benefactor at the time the gift is formally presented? But I digress...)

Now, go and buy that robe next time you're at the hotel.
