I have a question. I order room service a lot as I do not like to dine out alone. Marriott puts a 20% SERVICE FEE on the bill. I have asked the server if that is their tip. I have had a couple say yes and I have had some say a very small part of that. It is divided up with the cooks and others.. What is the truth and should I be adding additional tip. It is ultimately the company's money so I don't really care. I just want to be fair.
