I have shopped at Aldi and Tesco,both with short queues outside where everyone was patient and keeping their distance. Once in store though,a different matter,people coming up behind,stretching over to reach things and totally ignoring the one way system in Tesco. I'm in a mobility scooter so cannot just step away from people too close. In Aldi,waiting in the proper space at the tills,a lady stepped in between me and the person in front. I told her I was in the queue and that we had to space out. She just said "Oh!" but she did move behind me.
I saw a post on Instagram with a funny poster saying "If someone is close enough to punch in the face,punch them in the face." Oh,how I felt like doing so - not that it would have hurt them much with my weak wrists!
