Don't think it was as bad as you made it as they were just trying to poke fun at the time. You should mention to them not to do that next time and they'll catch on.
shouldnt have to mention it though i dont go to a site pay for the day for someone i dont know to pick my rifle up and fire it like a wanker as the guy rattled the mag off and they dont know me from adam,and fact of matter is bud i had just repaired the rif aswell that was its first outing so they could of ended up causing damage to it if my repair joob was off,also i had comms with them so they could of asked but no,to me thats unaceptable
A mans gun is like his wife - you don’t want another man using it. Mind you if my guns were like my wife then they would let anyone use them - then blame it on the drink
is a fair point, this is the sort of thing that should be implied is not something to do, not free game until someone complains.
guns being damaged is another very fair point, indeed for all they knew that's why the gun had been set down in the first place. for example an owner might have figured battery was on the way out and someone firing off a whole mag would push it over the edge.
