Of course, with the current restrictions, I'm happy to follow all the extra signs to keep everyone safe. As these change from site to site, I know this sometimes makes life more complicated. That isn't any excuse for the site staff to scowl at us and to be unbelievably rude just because their instructions are contradictory and inaccurate. On both occasions we tried to book in, the office was deserted, and there was just a misleading notice telling us to wait. When we finally did track someone down, we were blamed for the way the site was operated.
