How to make life easier for sitters

Hello everyone, this is my first time writing on this forum. After 14 sittings I have to admit that I am a little bit surprised by how many times I have to clean refrigerators that are very filty, need to make space for our food and to throw away expired stuff that have mold or a bad smelll ! I don’t mind doing some cleaning at all but I found it is a bit unfair to start a sitting like that and having to clean ++. As for having space in the refrigerator, I will take the advice that someone mentioned to ask them ahead to make a bit of space. Also, a few times, they are telling us to take whatever we want in the fridge, but most of it is expired since a few months or even years.
