Every night people show up to the ornate Forrest Theatre to watch the wildly popular Hamilton, which has been running since late August and leaves Philadelphia on Nov. 17. The show is long — almost three hours — and the theater’s old charm means there are few restrooms. Apparently in 1927, building designers didn’t think about the large bathroom demand from female patrons. During the 20-minute intermission each night, Heath estimates 200 women line up outside a lower-level room containing a mere 16 stalls.
