I generally stay at the same hotel every week and leave leftover beers in the Fridge (not a mini bar just a regular small Fridge) a couple of times I have checked out on Friday checked back in Monday, had the same room and the beers were still in the Fridge.

It used to be a rare occasion that I had leftover Beers even if it meant drinking a couple on the way to the airport.
On a side note used to Rent exclusively GM cars so I could use the seatbelt as a bottle opener.
