I don't even know if it was a church service per se, since it was a broader thing, but my mother's funeral might count because it ended with my siblings implying they intended to ghost me from then on.

On a less solemn but more bitter note, there was a Buddhist temple where I used to live even though I don't remember if I ever went inside or not. I have a single Buddhist friend, and he warned me (because he was not like other Buddhists) that other Buddhists' notion of karma was such that, along with seeing people with disabilities as having had a past life of sin (or the equivalent Buddhist loanword), some fear it as associative in nature and will go so far as not touch an individual who has a visible medical condition, which I'm the only one with (everyone else's medical history is invisible), and I remarked (referring to Joseph Smith having lived in the area) something like "at least Mormons treat those with respect who they deem as the equivalent to being cursed", which began a theological debate over why it's "meh" when Buddhists deem someone as cursed but "oh no" when those of us who are under the Mormon umbrella do. Nobody mentioned is hostile to me, but there's an air of backhandedness towards me whenever I'm around. Fortunately it was only ever relevant once.
