As it seems we need a bit of public support on this one.
Me, on Friday night. Went to a family friendly Italian in York. Our starters was taking ages - well over 20 mins - and dd was hungry and getting wired and was about 5 seconds from kicking off, big stylee.
I offered and she agreed. Fed for 5 mins on both sides then calmly sat down and waited - the food arrived 3 mins later.
I think one lady noticed and seemed to give me a smile afterwards. I think everyone would have noticed if i had waited till she was screaming like a banshee.
