FWIW, in my professional life, companies like ours make money and we earn our livings by problem-solving. We try to understand the whole flow before attempting solutions, to save ourselves wasted time and effort.
In the case of freezers that are packed, fridges that are dirty, etc., the problem begins with the HO, so typically it’s logical to start there. That’s exactly why THS offers guidance to HOs on prepping for sitters.
If the HOs falls short of such basic hospitality, then the sitter is left to deal with a problem the HO created. (If you’re a HO, the best way to avoid having solutions you dislike is to avoid creating the problem in the first place, as in not leaving room for a sitter to live comfortably, which can affect the care they show your pet(s) and your home. In this scenario, you have the most to gain or lose. Again, that’s logic.)
Note: People generally expect to have food storage where they’re going to live.
Meanwhile, THS says sitters are expected to feed themselves. That means logically if HO chooses to do more, it’s icing. So to expect food is above and beyond the standard.
If you’re a sitter left to deal with problems created by HOs, such as lack of space, you can always discuss ahead, plan workarounds or such. In the end, if a HO is upset that you needed food storage and dings you for it in their review, shrug. Most people will understand that you needed space and you are never obligated to eat someone else’s food just because they didn’t leave you space. If future HOs wouldn’t pick you for their sits over something like that, you’re better off, because they’re not considering your basic needs as a human.
Sitters who do whatever HOs demand are forgetting that THS is an exchange, an equal dynamic. We aren’t orphans or homeless people who should just be grateful to be picked and to accept whatever HOs offer or not.
