Somewhat, but if I try to think that Kogasa forgot to purchase from the other groups and circles, the issue become clear. (Yukari "manning" the booth [and we know she didn't] and to assume that would give her more time to move around)
It just hit me that if he left the announcement, we'd know who Ran&Yukari group are ;3
