I totally agree with this. Some shooters tend to not care about their surroundings, who else is shooting, who else is using the lane after they leave (leaving targets hung, not sweeping brass), not paying attention to their casing flying over the barrier into other lanes and possibly striking other shooters, rapid firing (which they know they are not allowed to do)... etc.
I saw a guy in a wheelchair there once and I had to leave because he was trying to adjust his chair while holding a loaded 1911 with one in the chamber and his finger on the trigger. I was in the lobby just waiting for the "POP". Shooters come in all the time that have owned their weapon for months (sometimes hours) and never shot it, read a manual, tried to reload it, clean it, etc. much less hold and fire it.
Are you suggesting that people are rude, discourteous, and inconsiderate? Say it ain't so!
