My husband is still working at age 68. He works part time in the Co-op. They have no protection either. There are no barriers between staff and customers, and in their store not enough room for a queuing system. They have someone on the door limiting the amount of people entering.
He went for his shift at 3pm and is now back home. The manager has a suspected case of covid 19 in another member of staff, she asked him some questions about his general health, and sent him home. He has to self isolate for 7 days.
He has a headache, but there is probably another explanation for that, as he has high blood pressure and suffers from stress. He does not have a cough or any other symptoms so I'm not unduly worried.
