Had parents like this time and time again, and the only advice I can give you is: people like this NEVER CHANGE! I think it would be wise to get rid as soon as you can fill the spot, until then reinforce your rules, make them pay late fees, for all late pickups, and maybe even give them extra charges for the supplies they are not providing that you are using for their child. This one doesnt seem like a good fit for any provider, or any GOOD provider that is!
