You can ask them to remove the bar items from the fridge. We usually take them out ourselves (so we can get our stuff chilling faster) and put them on the top shelf. Do not forget to leave a note saying "please do not restock fridge".
The fridges are the peltier style not a tradional compressor type like your fridge at home. This means that the fridge has a limited capacity to cool. Put your things in there as soon as possible because the fridge needs extra time to get things cool and it may not get things ice cold like your fridge at home. There is no freezer.
