A year ago, I watched my GF's dad put a load of 20 gauge birdshot into the ground 2" from his foot, right as my brain was telling me to yell at him not to have his action closed if he wasnt on the firing line.
I should have been paying more attention, as it was two newbies (GF and her dad) and I, with me trying to teach them how to shoot clays with two shotguns (his and mine). In hindsight, I should have only allowed one shotgun to be uncased at one time, as both my GF and her dad were the type of person that just had to play with anything they could get their hands on, and neither had taken a gun safety course.
I was helping him with his aim and swing and throwing a few slow pigeons. He had said he was out of ammo and walked back to the table to load up, so I started helping my GF with her stance (using the other shotgun), only to see him close the action of his Mossberg and fiddle with the safety out of the corner of my eye without his glasses on (he is practically blind without them, who knows why he took them off, his glasses were both protective and corrective). We all got quite a wakeup call when he was covered with dirt as I was starting to think about how to get him to stop what he was doing without causing him to look at me, as I was worried he would sweep me while trying to find the source of the shout, since he couldnt see squat.
Later, I found out that without his glasses, he couldnt read the lettering on the last shell in the magazine, so he thought it was the follower (as this was the first time he had used the gun) and that the gun was empty after trying to clear what he thought was a dud, which was really a new shell sitting on the feed ramp when he had the action open, he didnt see the old one eject so he dumped the shell in question into his hand thinking it was a dud that hadnt ejected properly. What an experience.
