Good question. I let him take my target and just used another one. Didn't say anything about it because it didn't bother me for some reason. When he shot my second target, that's when I got irritated and asked him to stop. I asked him to read the rules when the rapid fire started. I have no authority, so not much else I could do. I'm guessing a range officer would have asked them to leave.
Dam I just missed you. I left at about 3ish. Had to get home and go to bed. 1st night back to work since I got back from the beach.
We call them "tactical beach umbrellas", and they do work well for rain and the hot ass days where the sun is baking you like a piece of bacon.
