First Minister, you mentioned in your response to Mark Isherwood the code of practice around face coverings for autistic people, and you'll be very aware, I know, that as well as autistic people finding it sometimes difficult to wear a face mask, they can also find it difficult to communicate with somebody who is wearing a face mask, and the same would be true, for example, of deaf people who may need to lip read. Can you confirm this afternoon, First Minister—and I'm asking you this question in the context of a constituent who had an issue with this—that if a member of the public, an autistic person or a person with deafness issues, requests a member of staff in a shop to remove their face covering so that that deaf person or autistic person can more effectively communicate with them, that it is acceptable for the member of staff to do that, providing it is possible to maintain the 2m social distancing? My constituent's experience suggests that there may be some confusion on the part of shop staff in this regard.
