That is a MAJOR problem that all these books do these days. Everyone is on a first name basis with everyone else and in an attempt 'humanize' them... Everyone is always calling each other by their first names. So much Clark, Bruce, Hal, Barry stuff going on regardless of who's around. I mean... c'mon, you're in work clothes here. Be professional. you never know when Lex Luthor has a satellite focused on you...
