Kicked out of a shop for playing old school magic.
A friend and I signed up to play in the Commander league at an LGS. It was $5 and we each received a booster of the latest set. The idea was that we were supposed to form a commander pod with other players.
Instead of playing Commander, we decided to play Old School with ante for the boosters. Naturally, we were using cards like [[Contract from Below]] and [[Jeweled Bird]].This drew a small crowd because it isn't something magic players see every day. The event organizer found out, came over and told us that wasn't allowed and we needed to leave. I've never been kicked out before.
On the way out, I asked if we were being banned. They said no. We could come back on another day, but we had to play commander specifically and we couldn't play for keeps.
