Reminder that prizes should be readily available in the inventory of the host prior to the start of an event otherwise the legitimacy of the event is moot. Failure to comply will lead to the closure of the current event and restrictions + additional oversight placed on the host for any future events they may host.
I will let you off with a verbal warning this time. Further delays or persisting occurrences of event neglect will be escalated and the proper event staff and administration team will need to be involved.
