@LowLevel sorry to hear that
My shopping habits have changed as I don't like long queues, but that's just a personal preference.
It is possible to get online deliveries now; I have found that with Tesco the longer term slots are only open for vulnerable people initially, to give them first choice, but closer to the time, any slots
not taken by such people become available so I was able to get a delivery with about 4 days notice.
Also my local larger supermarket is back to being open until 9pm so I tend to go late when it's virtually empty. I would definitely recommend this! There is a particularly troublesome individual who used to hang around outside and is no longer able to, so it's a better experience than normal!
If I do want to go shopping during the daytime my local shop rarely has queues, and when they do they are quite short. The only downside of those queues is that those of us with good hearing can hear the high pitch noise to deter teenagers gathering, which I can put up with when briefly entering the shop but becomes annoying after a few minutes. I only had to queue once there though.
