Did you have a 1.5m broom or similar with which to enforce social distancing by poking people with it?
We scoured the Assembly Area for suitable in situ materials. Really only has to be roughly 1m as if you hold it in your hand there adds at least 0.5m. But I think we were more reminder prods and not physical prods. One of the joys of our events are the "sitting around afterwards in the sun/shade catching up. People in the main weren't hanging around but some were taking the opportunity for a well-spaced catch up.
