I feel your pain, what I could do at 45 when I started USPSA is a lot harder at 68. Yes, too many won't run a timer, paste (or walk with one paster to go to a target closest that has already been pasted) or even run the scorepad. They just want to shoot, improve their performance, watch themselves on video after shooting a COF, and shooting the breeze. It's all about them.
It does get demoralizing when you have so many newer shooters that don't read rulebooks or help out. They forget who will be running matches whenever we are gone. So I bitch at them, make a nuisance of myself, and hope they inflict themselves on someone else next time.
