I remember when I use to secretly drink vodka all alone in my room I would hide the empties under my bed and in the closet so I could throw them away in secret later. One day, a technician came out to work on our satelitte and no one informed me of this and I found out the guy had to go through my closet to access the cable. Turns out he had to move all the empty 750ml vodka bottles (12-14) and then he placed them back after finished... I was utterly mortified.
Happy to say there is no more hidden booze anymore.
