 MISC: As Martin and Cora are chatting in the lobby of Elliot Bay  Towers, Frasier exits an elevator from the right of the set to  "check the mail". Once he realizes that Martin has already got the  mail, he enters an elevator on the left of the set, opposite the  first elevator, to return to his apartment. If there really were two  elevator shafts facing each other in Elliot Bay Towers, one shaft  would have to go directly through Frasiers apartment, somewhere  between the front door and the couch.
