My wife went to the cinema a couple of weeks ago and sat in the middle of two friends. A day later one of them tested positive. A day after that the other one did. As a result, we were extra cautious and she did more regular tests, but none of them came back positive. She must have a great immune response, because we were sure it'd finally get one of us.
Incidentally, one of those friends, despite still testing positive, was asked to return to work as they were short staffed. Honestly can't believe the idiocy of management at some places.
