For anyone who feels this way about the grocery store, I'd highly recommend curbside pickup or online ordering. Some stores are getting rid of it, but plenty still offer it. If you live in a large enough city, grocery delivery can also pretty competitive in pricing if you're willing to negotiate on brands.

And if you have the luxury of time / a flexible schedule, figure out when it's quietest. Some shops in the UK are (or used to be) open 24/7, small hours shopping is where it's at.
