I think they make money. Here is the mentality of several people I have traveled with in the past...its late at night, I'm thirsty/hungry...need a snack...could get dressed and go to the vending machines and/or lobby to get something...I may or may not get a receipt (If I don't it comes out of my own pocket)...or I can just get up in my PJs open the mini fridge grab a $7 bottle of water and a $8 bag of nuts...I turn it in as an expense with my lodging...I'm not out anything AND I didn't have to get dressed or leave my room and maybe even a few extra Marriott and credit card points.

Crazy stuff...I try to spend my companies money as if it were my own (Lowest fair possible for airlines and Fairfield as often as possible)
