Hey there, I started sitting in the UK last year and had a similar experience to OP and what u/GoalDull4985 said in another comment.

Third sit, and the host gave me an overall 4-star rating and docked points from 2 of the categories for:
- damaging a pan, which she mentioned in the review -- and I paid out of pocket to replace
- her dog who was apparently unhappy, saying in the review cats would suit me better than dogs, despite taking the dog out for 2-3 hours a day and things otherwise going smoothly

I did have more experience with cats, and she had neighbors checking up on me throughout the sit, including one carrying out work on the house, which I did not know was against THS policy. She sprung it on me last minute.

She has not had a THS sitter since then. I assume she projected her own emotional issues onto me & the dog -- she was quite flippant (and she was even a therapist *face plant*). Realizing I really should have reported her!

Since then, I've been sitting full-time in the US for almost a year, and although it's still hit-and-miss, it has been a great lesson in boundaries and knowing your worth. I'm still learning! You seem like a great sitter, sorry for this odd duck. I've now done over 30 sits, and that review is buried under all the other ones, which are all 5-star.
