I live in a small town and a small group of us moms make up our preschool board.  We recently had one mom (whom is known for causing problems) informed us half way through the semester that her son had speech therapy almost every secong Pre school day so she would only like to pay us half his school fees.  We told her had we known the situation before school started perhaps we could have worked something out but by letting us know half way through, after we had already done up the year's budget and what not, we were not able to give her a discount.  She got mad and pulled her son out and asked for an invoice for half the fees, which we will give her because we're not prepared for a big face off.  And seriously, our fees are so cheap.  It is 120.00 a semester (for 2 half days of school a week).  When you register for swim lessons, soccer, etc, you don't get a discount if you can't attend a bunch of the classes.  What do you think?
