You can skip the service charge by purchasing your ticket(s) at the door / Box Office the night of the show. You do however run the risk of not snagging a ticket if the event does sell out.
You can also snag a ticket for a future show on any show night. The box office will be able to make these sales 1 hour after doors open. In other words, let them take care of the current show then they’ll get you sorted.
