I went to a cafe at the weekend about 1ish, on entry I gave my contact details (no app). Got my lunch I was probably in there for 30-40 mins, which got me thinking...
If someone went in there before or after my visit and went on to get a positive test they I would assume let the cafe know. Does that mean that anyone who was in that cafe at whatever time will be told to self isolate? The cafe have no idea what time I arrived or left, I’m confused!
