For non-locals it is moot; credit cards would share home billing data. Not a tourist's hotel/temporary whereabouts.
Time is of the essence for contact tracing.
It also requires an honest reporting on the tracing form by the attendee.
New contact tracing norms will add up quickly as new expenses for the production: the house would need to open by 60 minutes (more?) prior to curtain to facilitate protocols. Most Bway houses open at 30-40 minutes prior to curtain unless there's a hold from BOH.
That means all FOH staff have an earlier call. And I'm sure the usher's union will require an extra duty payment: temperature scanning, collecting data from patrons, etc.
Bar needs to be set up earlier. Merch, too. Infrared. Everyone.
And that means BOH needs to complete sound checks, etc. before the new house opening time. Everybody would have an earlier call which means longer length of day. Also means less turnaround time on double-show days. For a show with a longer running time, the matinee curtain may need to move up to allow for new post-show cleaning protocols for both BOH & FOH.
