Other issues to be aware of.. housekeeping may charge based on what is in your trash can without even checking the fridge. Once I bought a coke from the vending machine outside, and they charged me for it when I never opened the fridge.
The other time I got charged was when I was not a Platinum member but my colleague who was offered me a soft drink he got complimentary from the lounge, and just because I had it in my room (I didn't even open it because I ran out of time), they charged me for it. I let it slide for that situation because I realized that fine, I wasn't entitled to that drink for free anyway, but it just made me surprised that it even happened because it could have been a valid own personal purchase drink from outside.
