I didn't have to show the guy anything, but the conversation would have gone something like this...
Him-"I need to see your class three license"
Me- "I don't have to show you"
Him- "You don't have to shoot here either, play by the rules or go home"
Me- "Ok, bye" -or- "Here's my papers"
I didn't feel like showing the guy, but EVERY range within an hour drive of my house (4 ranges) ask to see the F4's. This particular range is the closest (15 min) so my ability to continue using that range is important to me. Thus, "here's my papers" even though it's not necessary.
