STBXW was supposed to take D to get her hair cut last weekend. I was going to pay for it, dropping off money with MIL on Sunday. She didn't take her, claiming lack of funds (apparently, they went out to a nice dinner, instead). So I took her last night. I sent a text asking about specifics (how much to take off, etc) and got back sad story about how she was supposed to take her, etc.
Then she asked where I was taking her and she started screaming that they were going to ruin her hair and threatening to call her lawyer (seriously). She called the hair place and told them if they cut our daughter's hair, she would call the police on them (seriously).
