"I'll carry it, sealed," Retief said. "If it's trapped for destruction, I suppose—" "I've heard of these Jorgensen's Worlds," Retief said. Overall policy calls for a defense of these backwater worlds. Retief opened the envelope Magnan handed him and looked at the tickets inside. Retief stood up. "I'll tell you what," Retief said soberly. "But—" Retief picked up his suitcase and walked away toward the glare sign reading To Gates 16-30 .

 The captain’s men as well as himself are too scared to confront him, so he leaves him be.
 The captain knows that the Soettie will be able to handle him later.  The captain’s men as well as himself are too scared to confront him, so he leaves him be.  Retief remarks on the Uniform Code, and the captain doesn’t want to have legal issues.  He doesn’t have time to deal with Retief, so he leaves him be.
