I don't understand your point. Are you telling me that rules like you must spend €9 on a meal of substance and you can't spend more than 90 minutes in a pub are easily understood, implemented and enforceable for the majority of businesses? Oh and if you do this, you only have to do 1m social distance.
No, I simply asked what measures you think they should introduce?
If we want to focus solely on the risk and scientific advice, then we should keep pubs closed for a lot longer.
