HOW can test & trace work - when sitting in a café this morning a family of five (including three kids) entered.

The gentleman was drinking from another outlet’s takeaway cup, and ordered one drink for the wife/girlfriend and then left. No masks and no QR code taken.

If I am unlucky enough to be contacted later on by the test & trace system how on earth is this family going to be tracked? Were they locals or holidaymakers?
