I totally agree, and never add anything to the tip line on a room service bill. I'm already paying 20% + about $2 at most places to have the food brought up to my room. There is no way it costs the hotel that much to offer room service, and if that service charge isn't going to the employee who delivered the food, then the food service employees need to have some serious discussion with the hotel's management about why they're not receiving the gratuity that the hotel is automatically charging to the guests who order room service. I don't see it as my problem to solve a compensation issue between the hotel and its employees.
