Yikes !!!!! Borrowing from the deposit ???!?!?! No way .... all payments should be in advance payable in cash or EMT only no cheques .... I wouldn't trust this family for one minute! Not worth this headache for one day a week even if it ends up being more days that just means more headaches. If he doesn't pay at pick up then say see ya later and if he does pay then I would tell him for next week he has to pay at drop off and he has to pay back what he used out of the deposit as well.
