For the first time I can remember, the two clerks at my station today were both under 30. Now, as an oldie myself, yes I can and do use QR codes etc. but it was interesting that they were doing the checking of the list and scanning and the 'mature' helpers seemed to be doing more of the guiding people on where to go, making sure no-one ran off with the sanitiser etc.
Maybe it was coincidence - but it was nice to see compared with the pompous gits you're usually faced with (perhaps that's just my village/tiny town though)
