Each sitter has to decide for themselves how to interpret grey areas of THS. That’s true of many things in life beyond sitting.
For me, I will always have boundaries and not be willing to let people take advantage of me, whether sitting or otherwise. Some people hesitate to do that, focusing on how hard or awkward that would be.
What I’d say is, step back and consider how unnecessarily unpleasant life can be if you let unscrupulous people take advantage of you and you realize that you let them, because you didn’t stand up for yourself. To me, that makes it a purely logical and obvious choice.
Plus, it can be done without getting ugly or aggressive. It can be neutral, matter of fact or friendly. If you’ve not practiced it, maybe it can be hard at first, but I guarantee that you can get good at it. And if you practice it, you’ll end up wondering why you didn’t do it for yourself sooner.
As for THS specifically, I’m never going to pay and let anyone exploit me. If it came down to it, I’d rather never sit again than let that happen. That’s a boundary I wouldn’t compromise or allow anyone to cross.
When I say I won’t sit without a welcome guide, it’s not been a problem. I’ve never been anything but friendly about it. Haven’t had to be at all. If it ever became a problem, that would be red flag to me of a potential host who makes it an issue, who doesn’t want to do their share to help set us up for a good sit.
Why shouldn’t they care about how their pets and home are cared for? Why shouldn’t they provide info about such? If writing that down or otherwise capturing such, like on video, is such a hardship, what does that say about how little they care about the sit and their sitters? I have absolutely no interest in sitting under such circumstances. To me, why should any sitter allow that?
Some sitters might not care. Their choice. But what often unfolds from such are tales of sits gone wrong. And it’s easy for such things to repeat for such folks, because unscrupulous, entitled or unreasonable people tend to gravitate toward easier targets. They don’t typically try much, if anything, with people who stick up for themselves, because they realize that they’re not going to get anywhere.
Remember, people like that probably didn’t start doing it yesterday — they’ve had practice. They know with whom and when they’re likelier to get away with crap. They read who’s more likely to enable them vs. not. I’d suggest not enabling them.
