A day off when all your friends and family are at work is not always the greatest fun.
I was explaining to the fella who, in seriousness or jest, appeared to be under the assumption said workers work 7 days a week and never get a day off, and appeared to be using this as a reason to go back to Sunday closure (and the Long Dark Teatime of the Soul). I suspect he may have been having a little joke. At least, I hope so.
I know it isn't fun to work Saturday and Sunday. I did that myself for 6 months way back when. I've done nights as well.
If our economy ever becomes sufficiently buoyant, and people find thay can obtain employment that does not require they work on a day or at an hour that doesn't suit them, we may find there is an economic pressure to shut shops on a Sunday as the staff salary demands would make it uneconomical. Saturday afternoon too, perhaps.
I suspect, however that this coming to pass is about as likely as a new series of Love Thy Neighbour being commissioned, staring Jim Davidson and Big Narstie, and it winning a Bafta.
