Dc have covid and were in London with ex this weekend during the period which test and trace want to know about. I can give vague details on their train to and from but not accurate times (I didn't take them - ex can't tell me). But he took them on lots of buses and underground journeys and cannot give me any kind of accurate times so it seems utterly pointless to spend ages filling them all in on the website questionnaire.
Realistically I don't believe that even if they had the accurate bus times they would do anything useful with that info, but without accurate times it is just a waste of time - right? Or am I wrong?
