I had a similar experience with a nail technician I use occasionally. I took my sister, who has learning difficulties, for an appointment there, she knows my sister and my sister is happy to go there normally. I explained to my sister that she would be wearing PPE , like the hairdressers she had been to the previous week, that she would have her temperature checked and a simple health questionnaire. When she came out my sister said she didn’t experience any of that, so I questioned it with nail technician. She said the same as previously mentioned, wasn’t compulsory, needless to say we are not going back there!
I have booked my sister with another beautician who does it to the letter. Also what is more disturbing, my sister was shielding during lockdown as she has health issues.
