Clue: Guide snubs one, so has he lost it? (4)
Answer: PLOT
Explanation: Definition: it?
Last in, and I cannot say that I like it: P[i]LOT ('guide') minus ('snubs'?) I ('one'), and if your guide had 'lost the PLOT' he or she might snub you. It seems so far-fetched that I feel I have missed something. Of course, in looking at 14A, I had hoped it might give me some help here, but no such luck.
