That way you don't have fools sweeping you with their muzzles or handling their firearms while you are down range changing a target.
On the other hand, I know one guy that we are all fortunate that he has his own place. A very nice fellow, but I took him to a square range along with his new wife and he was a "It's not loaded" sweeper.
“we don’t allows assault shotguns on the range. You sir need to get a gun like your friend here, an over under break action”
Probably rare, but the opposite happened here once. A wheeler dealer type found himself with a Deal on a real Trap gun. He thought he would give it a try before he traded it for something else. A hunter and plinker type, he did not break a lot of targets and was hoorawed for bringing out a gun he did not excel with. He won't be back.
The staff at the local indoor lane rental range are generally pleasant and welcoming.
When they first opened up, a friend and I "joined" and went in to shoot. We hung targets and ran through a series of drills, stuff we could do for IDPA practice without holsters. When we were leaving, one of the employees whispered to my Lady companion "What kind of professionals are you?

The other, the range officer had a drill sergeant approach and looking at the clientele, I realized it was needed.
