I have dined several times this year with a group of 6 friends. I am single whereas my friends have atleast one kid each. When the bill is split, It is always split up amongst the adults so I end up paying for what I ate plus a portion of the children's meals. There are typically eight to nine kids each time. How do I bring up this topic and come up with a fair way to split the bill? The fact that we order family style adds to the problem.
