I pretty much agree with the comments here (even Matt)
Unless there is a ruling saying that shops cannot sell X, Y & Z because they are not essential then who are we to turn down a bargain chainsaw (AMA Express) or some Speedos (Matt) from Aldi?
They could tape off the clothes isles or office stationery and greetings cards if they are deemed non-essential so then there isn’t the choice to buy them.
Dog walking is good. I take my old dog Woodbine out for a drag very early on and then again late at night in case nosy Nora grasses me up. But there are gangs of feral kids around and someone needs to drag them and the Emos and the like off the street.
Question. Is booze essential?
