Between changing targets on the rifle range the female employee commented on my shooting without me asking her opinion. She told me that I was shooting too high (roughly 2 inches high @ 100 yrds). After I explained that was my intent she awkwardly left me to place a new target for the next rifle I intended to shoot. She then returned to tell me that I was placing my target too high on the stand, which hangs from the ceiling. I asked if I could place my target on a larger one I saw in the trash. She confirmed that this was acceptable. I began placing the two targets together on the stand, to which I was instructed to tape the targets together. She again awkwardly left me to shoot. As I was moving my supplies to the shooting bench for this final target the male employee entered in a rage to tell me that I had better follow the rules or he would show me the door through the wall (cinder block wall). He then followed with a rude instructional session telling me that my target must be centered on the ranges standard size target or it would cause a safety issue. As I was leaving the facility the male staff member asked me to never return. I would recommend that you consider this an unsafe shooting venue as the staff carry concealed weapons and in my case threaten customers with bodily injury. In the two times the female employee made comments about my shooting or target, she did not attempt to convey that the targets must be centered. Please consider the safety of your fellow shooters as well as yourself and not give this facility your money.
