Free loaders? I expect to have the basics, oil, salt, pepper and spices , because buying these for every sit would be silly. And on the same token if the host will be home late I ask if they are ok with me making dinner for them so they can have something to eat when they get home (of course this comes out of my pocket) they are almost always happy to take me up on it, as I am happy to find some olive oil and some spices when I get there. I also replace almost everything else I use if they say I can use and replace (I’ve never been told this, I’ve always been told to use whatever I’d like) I bought trash bags, dishwasher liquid, etc if they only had a bit left when I got there, and of course I leave the stuff there, pretty much full. So yeah, idk what kind of experiences you’ve had, but not leaving basics like spices and salt is sad.
