Or he asked for two place settings to eat at different times
That being said there was another woman of interest that the police are looking for and she could have been in there eating with him.
As a proud "graduate" of the Ritz-Carlton Leadership Center I can say this type of thing is something a good roomservice person would avoid asking about at a high-end property. One of their mantras was that you don't take an inconsequential issue (like the number of people in a room) and turn in to a potential negative. They actually even used roomservice as a specific example. You make a best guess and avoid these types of scenarios:
a.) The guest is a chronic overeater and will feel guilty about ordering enough food to make you assume two people were in the room. In his angst he gambles less.
b.) The guy has a hooker in his room and will be forced to acknowledge there is someone else there when he's supposed to be alone on his business trip. In his angst he gambles less.
c.) The guy came to your resort to hook up, failed, and when he has to admit to one place setting you are reminding him he's alone. In his angst he gambles less.
d.) This is the second anniversary of the last meal he had with his wife before she was killed by an escaped alien at Area 51. By having to say he's alone he will gamble less.
The attendant should err on the side of caution and in the unlikely event the guest complains about too many place settings you simply say you wanted to make sure he had a full place setting for each course/meal.
I know personally at some high end properties I've received a full place setting and ice water for a soup and another for a sandwich.
