Have a look round at how many social distancing signs there still are. Signs don't get updated, so is that 8am opening the actual opening time or have they not updated the sign? And if you make an appointment for 8am at the other side of a (not) time change. Does that appointment change, or do you need to attend an hour earlier or later?
