What stuck out is:
Most of the time I like to write down once I arrive you know um the time I drop them off and the fare that they paid.
1st interview, retracing route. Fare shown on meter when he says 'This is where dropped off' is $6.55. And interview trip possibly at busier traffic time. So where did Wheeler's trip come to $9 - $10? At a very slow traffic time. Some side detour, or mis-recollection....
Also 1st interview: [paraphrase] '10th-Orange - 11th-Orange...route all of us take to Hotel Dupont area or any other buildings in that vicinity.' 2nd interview: very specific that Wheeler said to Hotel Dupont.
TIP: Probably handed him a $10 bill and said keep the change.
