My hairdresser actually warned me not to go into her salon because she doesn't feel the stylists and manager are careful enough, so she comes to my house and cuts my hair in the kitchen with my windows open, both of us fully masked.
She caught Covid from an unvaxxed client and her PCR test was one of those sent to that dodgy lab in Wolverhampton and it came back negative, so she continued to go to work and inadvertently infected her husband, 3 children, both sets of parents and a few clients. All her clients' contact details had to be given to Test & Trace.
I would be very careful, especially with the Omicron variant doing the rounds now.
