Need some advice on how to deal with a new client...

[MunchkinMinder]

So I need a little advice on how to proceed...

I have a set of siblings who started today...the kids are overall fairly good and should be a fine fit once settled into the routine...The mom on the other hand I'm starting to think might be a whole other ball game I had agreed to a slightly lower monthly fee in exchange for her supplying the kids food which she asked me to write up a list and she would buy foods that fit into my meal plans this morning she shows up with 3 items off my list and a handful of random items like pudding, jello, juice, etc. which I don't serve to the kids at all. Then an hour and a half after dropping the kids off she e-mails me asking to change our payment agreement to fit her pay days better and if I agreed I would go from being paid in advance to after the fact.

I have a clause in my handbook about termination and one of the reasons for immediate termination is false information given either verbally or in writing. Would you consider it the mom providing false information by her signing the payment agreement and agreeing to provide all her children's food following a shopping list provided by me then turning around and on the first day going back on it all? I am seriously considering cutting my loses now before I get burned too badly! Thoughts??

I am getting a whole slue of red flags going up and I'm just wondering should I just cut my loses now or tuff it out and see where it goes?

P.S.- I have already e-mailed her back and told her that I am not willing to change our payment agreement that she had already agreed to. I feel that if she wasn't able to live up to the agreement then she should have been upfront with me and I have no idea what to do about the food situation
