Sunday closing a good thing? What are you talking about? Talk about rosy tinted glasses!
I remember my mum having to trundle around shop after shop for hours, multiple days, when we were kids to get everything the family needed, usually after school whilst my dad was still at work.
Sunday closing only works if you have a stay at home parent to go to the bank / do shopping and household chores whilst things are open during a working week.
It's bad enough having a GP surgery / dentist that's only open very strict times, but we just about manage it (taking half days here, half days there between us).. if DH and I had to fit in haircuts, Dr appointments, post office stuff, paying bills, buying presents, buying DCs shoes/school uniforms, going to the bank... all fitted into the working week, I've no idea how a modern family structure would fit it all in.
Actually, it's one reason why I'm in the process of changing my bank at the moment - the branch near to us doesn't open at the weekends, and as far as I know never has/never will - and neither DH nor I work continuously / reliably near one, which has always made dealing with any problems a total pain. So I'm off to find a bank that's not stuck in the 1950s and realises that the majority of families doesn't have a SAHM to do household chores in the 9.15am - 5pm Mon-Fri timeslot they're open... which is when DH and I are usually at work.
