At risk of sounding like a bitch here…. Get a grip of yourself. The guy absolutely did not ‘deffo have it’ you sound like a moron saying it. I currently am on day 10 of having covid. Was it pleasant ? not particularly no, I had it worse then the rest of my family but here I am still. I am worried about other things now but that is anxiety for you. I am absolutely sick of culture of fear and suspicion that the media and governments have tried to hammer into us about covid. Look at you because a man looked at you and was buying cough drops !!!!! Did no-one buy cough drops before covid no ? Have all the other little bugs in the world magically disappeared ? Walking past someone even if they had covid wouldn’t give you covid. Most doctors agree you need some kind of direct contact with them like a conversation face to face or have spent some time in the same vicinity as them. You walked past a man, whilst wearing a mask, whilst vaccinated. Honestly stop being ridiculous
