I know very little about golf but suspect that there is a worry about the clubhouse on courses rather than the open links?
Same for commercial fisheries with a cafe and shop?
When we re-opened following the last lockdown it was subject to strict guidelines which Golf England, the kind of Angling Trust of the golfing world, had agreed with the government.
In our case it involved measures such as implementing a pedestrian one way system around the entrance and exit to the premises, only one person per buggy, removing rakes from bunkers so that they can't be touched by various different people, turning the holes cups around so that balls can't drop into the holes when putting and banning flags from being taken out amongst various other things such as hand sanitisers etc.
As always it wasn't the measures that were the issue, it was getting people to observe and adhere to them and ironically it would appear that the older players, and the ones which are more susceptible to a bad outcome should they contract the virus, are by far the worse for not complying.
You would give them the benefit of the doubt and assume they had momentarily forgotten but when you see two people tee off, one on foot and one in a buggy, only to then see the one in the buggy then pick his mate up halfway down the fairway when he thinks he's gotten away with it, you have to wonder to yourself just as you do when you see the customary handshake still going on after putting out on the 18th and players picking up and throwing other players balls back to them along with things such as mass gatherings in the car park.
To be fair we do enforce it but it's seldom met with a pleasant response... Ignorance is bliss, as they say!
