I kind of agree with both sides. Yes it does not cost much to buy a packet of chip not really a hassle.
BUT if you are having a kids party you are supposed to supply afternoon tea. I would only be buying them something very small for each child say $5 for each child and then a packet of chips for afternoon tea.

i don't understand why are they spending the money of hiring a hall but can't supply afternoon tea!!!!!!!!!!!!!!!
