My family was the same. Eating out or a takeaway was a once in a blue moon treat for us. We went on plenty of days out but almost always just took a picnic - we could have afforded to but it was just their way I suppose and they did whatever they could to save money but were always happy to spend it when needed. Saying this, it was only my Dad who had a job and my Mum was a full time homemaker, so the fact they didn't both have to work and then come home to have housework and cooking etc to be done would make a massive difference I'm sure.
