From my understanding any NHS setting you have to wear a mask but unless its busy / I am going to be close to someone I don't due to being heavily pregnant and having bad nausea and wearing a mask makes this worse.
Went into the pharmacy today and a man in there already told me to put a mask on (not staff) I ignored him and was stood at least 4/5 meters away!
He then proceeded to shout at the staff behind the till that I wasn't following the rules and he is vulnerable 
The lady behind the till turned to me and said you are required to wear a mask unless exempt to which I replied then why aren't any of the staff, she didn't know were to look and another member of staff was coughing into their hand then proceeded to stock the shelves.
So the man then started on the staff members and said he was reporting the pharmacy!
AIBU not to wear a mask when the staff don't bother to either?
