INSPECTOR: Yes, Mr. Croft - in the stalls bar at the Palace Variety Theatre...
GERALD: I happened to look in, one night, after a rather long dull day, and as the show wasn't very bright, I went down into the bar for a drink. It's a favorite haunt of women of the town -
MRS. BIRLING: Women of the town?
BIRLING: Yes, yes. But I see no point in mentioning the subject ....
Eva Smith, by the time she encounters Eric in the Palace bar, seems to be working as a prostitute, and indeed, the fact that the Palace bar is a location known for prostitutes looking for business is here partly mentioned but partly suppressed. Moreover, this information points out the streetwise character of Gerald Croft, and it might even lead to questions about precisely what he was doing in that bar, at night, other than just happening to "look in" after a "dull day" and having "a drink."
