Your menu is fine, she's just looking for a reason to bitch (pardon my language). I have one like that too and agree with Judy that the parent feels guilty about leaving their child and wants to look better than you. I have one like this too, she complains about EVERYTHING yet brings her kid here every single day. Don't let it get to you. I'm like you in that I keep her because I like her child, not her and I really can't afford to let her go. Advertise though, and replace her when you can. Until then, just know that this is her problem not yours.
