I went in a few shops yesterday in Edinburgh and noticed mask use was still fairly high in shops (one bookshop was universally compliant, other than myself). My train in each direction was more or less totally maskless though.
I've noticed some big shops still have dedicated exit and entry doors. Not even sure if they had those before all of this. One of the larger Tesco in my area has a huge entrance, with very wide doors, but still has temporary signs in the window saying exit and entry, yet they have removed the hand gel and mask signs. The annoying thing is if you're approaching the store from the car park, the exit is the closest logical door to enter the supermarket. There used to be a wall of produce artificially placed to prevent you from entering the store from the exit side and vice versa, but that's been removed, meaning they have a wide open entrance which you can use either side of, but with tatty, long past their prime, signs stating otherwise. I got bawled at by someone (not staff) today who crossed into my path deliberately to tell me I was entering the store through the exit. I said yes, this is the door closest to the trolley park and my car and then continued on my way. No one said anything to the people crossing over and exiting through the entrance.
