You should have sucked it up and played one more session, thus giving you a chance to give your email to the other players and arrange to run a game for them.

Now they'll probably be lost to the hobby.
I know that was my original plan, but I was just hired as a first year elementary school teacher, and once school starts I know I won't be able to make every week. That really leads into an important difference between how I imagine Encounters runs in other stores (a sort of rolling admission, come each week if you can, a certain amount of people leaving or staying and everything being very relaxed) and the shop nearest me, which advocates groups staying together for the whole season, and actually pushes player achievements as part of a competitive scoring between tables, the prize being like a $1000 dollars or $1500 store credit at the end of the 13 weeks for the ones with the most points.
It's another huge turn off for me, honestly, but I thought if I ever DMed there I'd kind of glaze over that part and foster a more meaningful experience instead of one dude with a checklist making sure we hit three damage types on an enemy, or held a longer-than-needed conversation with a minor NPC, etc.
I think I've also come to learn that I don't particularly like or want to spend time with every person attracted to this hobby. There are a lot of hardcore people with very set notions about everything... and some of them smell funny.
Have they been lost to the hobby? I hope not, but maybe. I don't think they're really experiencing the game as I've understood all these years, though, and it's sad, but I'm just not in the position to readily change it. If I see them in the future, though, I will extend an invite to a home game.
And for the record I didn't expect the guy to be there and then confiscate the sheets lol. That was kind of the last straw for me.
And I really don't want to knock the state I'm in, cause I bet there are dozens of other shops that do things right, and I know there are great home games, but I guess it wouldn't be hard to backtrack my earlier posts and find out I'm from New Jersey.
