The doorman who?
The doorman who's tweeting about this terrible joke.
The exchange above is no laughing matter, and some tenants in New York City are finding their relationships with their doormen just as unfunny. That's because some of those men and women who faithfully open doors, carry things and make conversation with tenants could be the same who are Googling tenants' names, tweeting about their conversations, and even writing books about them without the residents ever knowing.
The kicker is that tenants who unwittingly stumble into these situations might not have any recourse but to keep to themselves.
