It’s an infringement on people’s liberties
Neither the information commission or -um- Liberty share that view. They say that in pandemic times, certain aspects of data handling can be modified/suspended, so long as it can be shown to be necessary and proportionate. As track/trace is both those things
and it will be very difficult to practically manage
Not unless you choose to overcomplicate it. Just have a decent signing in point on entrance, and lock the info away when premises close. Maybe in a sealed, dated envelope, only to be handed over to an identified public health official,who needs records of a particular day. Otherwise destroyed after a period (min two weeks)
I don’t understand why it would apply in pubs and restaurants and not every other single retail outlet across the country
Likelihood of being close to someone, perhaps shouting over background noise, for >15mins
It's pretty obvious, really, and I suspect speaking for effect, simply because they don't want to do it, rather than real difficulty
