Purely anecdotal, but the number of people out and about in our local shopping area seems down quite a bit in the last couple of week, maybe as much as ~25%. I can say with certainty that we have not gone into as many shops as we used to for casual purchases. e.g. we often popped into one of the bakers for a couple of snacks (cakes, pastries etc) as we made our way home after our daily walk - not been in once since the mask rules came in. The other half often went for a browse in the craft shop when passing and bought something probably 1 in 3 times, again she has not been in since the mask rules.
