I shoot at a public range occasionally and move or quit shooting if it is necessary and warn spectators that my flinter will blow a lot of hot sparks out to the side.
At a public range you will see all kinds of folk, 99% are considerate and responsible, every now and then a half wit bozo will show up. One guy took a shot with his deer rifle while the rest of us were down at the 100 yard bearm pulling targets, when confronted he said he wasn't shooting in our direction only off to the side. We collectively convinced him it was time for him to leave NOW! He did when confronted by 5 or 6 very angry folk.
