Thanks for your comments. We were recommended the event by our local LGS who said there would be something for everyone there, from new to veteran. The issue wasn't with the event itself. It was with the people. Every time we were approached by players, or when we approached others asking for a game, we explained the kind of game we were looking for to every new person who sat down with us, and they agreed to play on those terms, knowing these things, agreeing to play slower, to explain cards as they came down, to be respectful. Some people, after hearing what we were looking for, declined politely and said enjoy the rest of the day. That was totally fine. We didn't force anyone to play by our standards. The issue was that the people we played with agreed to what we laid out. Then proceeded to do the exact opposite.
