Well, it would be hypocritical to use any Sunday commercial service IF your reasons for wanting Sunday to be a day of rest were religious and you believed this was the day God rested, therefore it would be sacrilegious for anyone to work on this day.
This is not my objection to extended Sunday opening, however.
And the key word is extended, being that shops and supermarkets are already open on Sundays.
Of course I occasionally use shops/ cafes on a Sunday. But I like that they shut early, and, on my high st, most are shut all day.
It's quiet, more peaceful, and if that makes Sunday a good day for pulling back from the material obsessions of day to day life, and if it encourages a bit of spiritual reflection then so much the better.
I used to work in theatre (so Sat and Sun-theatres are dark on Monday so that was my day off) and have worked in bars etc, but going into those areas I knew full well what the hours would be.
Incidentally weekend matinees in theatre can be fun because there is a festive atmosphere, due to the fact that for the majority the weekend is a freer time.
Incidentally I had to change my whole career after becoming a parent, because there was no way I could do the hours anymore.
At least when shops shut earlier on a Sunday people know they are going to at least see their kids in the afternoon, and can plan stuff-in retail you are usually not given the same rota every week, and often only find out what days you are working the week before.
