True or friends who visit after their working day arriving at 19.00 and having to go 1.5 hour later is not that good either. We have a select group of people that visit at times all vaccinated through their companies. (i know it does not totally prevent the risk but lowers it).
But the 9pm rule is mainly against illigal bars and parties.. i think moving it to 10pm would still keep that in check while giving more time to more safe visits.
