Unlike official trap because they not work weekends and able come in without make believe back story. Unlikely be general public person trying catch you out unless you ticked off someone and they trying make you break rules to be closed down.

Most likely desperate parent - not really care about who takes child since no background checks would be done before 7am Monday and no references speaking to. Will say if she has no respect for your weekend, or the regs you need follow, it not likely a client you need.
