At the few matches I've entered I noticed quite a few experienced/accomplished shooters do not help pick up casings nor tape.... but they'll gladly take theirs when others hand them over.
I know some don't take home casings or leave their throw-aways, but is it etiquette for everyone to tape and pick up casings or is it a random thing? Or have the seasoned shooters earned the right not to do the aforementioned?
Or am I such a newbie that I show up early to set up, stay after to take down and pick up as many casings as possible for everyone? Is it a do unto others type thing?
