but fancy going out of your way like that, to message someone to say they are going to slander your business, for something that happened to someone else she knew. I'll bet this lady is really missing the good old covid days when she could go around and abuse people who weren't wearing a mask. And sounds like it wasn't enough to warrant it anyway, "not responding to call light" could mean overworked nursing staff were busy with other things. sheesh. my MIL worked in an aged care centre, I would never say a bad thing about how hard those nurses work.
anyway, off topic, sorry. Glad she apologised to you, that is somewhat redeeming.
