I don't experience this, most archers spend the time standing around their bows having a good chat before they go up to the line to shoot, a few chasing scores will retreat and sometimes for good reason, as a lot of the banter about the days shooting and how it is going, that last end etc. can be quite negative.
I have used a fishing brolly and a small tent, in reality unless it is cold and raining cats and dogs, it just serves as a place for my kit and a shelter for the many ants nests. When the forecast is dry I just take a chair. I do think the quenchers are too big and create a barriers not just because of width but also height. At ?60 I could understand why they became popular but now at ?139.99...
