As the chief salesman Barber is obviously going to ramp up the fear of missing out on tickets so that he can sell more memberships, but that is hardly uncommon practice. next season I think the fixtures are considerably less attractive than last and I do not think general sale will be a problem...
I really think that next season tickets will be on general sale for all fixtures. I would be stunned if we had members only sellouts for any game other than a promotion/playoff clincher. I think there is a very good chance you will get your tickets, and I hope you do.
