it wouldn't have to cost ?150 for two evening meals plus drinks and snacks
Modest meal in a pub + drinks (soft not much cheaper than booze!) for four (and the kids always want dessert) can easily be ?50. Coffee/juice & cake for tea or elevenses, say ?2 for drinks and ?2 - ?3 for bun etc. x 4 there's another ?20. You'd be amazed how quickly it racks up with a family of four - actually, now I think about it, ?150 is really a very modest estimate!
