Some people shoot without any hearing protection on a regular basis, and to them, there would have been nothing wrong with the situation. I prefer to not hear ringing for the next week, though..
Me too and I've had my own ears "rung" both just because I didn't know any one else was ready to start shooting and because didn't expect to be making on go bang. Didn't enjoy either expirience. Fortunately both weapons were pointed in a direction a person wouldn't mind shooting what was in front of the gun at the time despite there was at least one person or more in attendance that didn't expect the weapon to be fired.
I sure didn't "give them reps" just because they admited to it. Gave 'em somthing but ya couldn't call it "reps".
