So it was an event to encourage non members to commit to paying the monthly membership thing? (what used to be called buying a season ticket) I think they need to try harder than meeting a few players, Roary and Amber, some food and drink which I presume you had to pay for and a raffle.
I doubt there was a run on memberships yesterday morning, but the event was quite obviously to show some sort of extra benefit of being a member, the food and drink was at least free.
