Maybe Whaley's passenger got out at the 500 block of North Beckley because that's where he was going. Or even south of there as Whaley mentioned he was angled south when he got out of the cab.
Whaley's passenger did not get out at the 500 block. The passenger gave the 500 block of North Beckley as the destination when he entered the cab, but once the cab passed the rooming house, the passenger told Whaley to stop and he exited the cab a couple blocks short of the original destination (and about three blocks past the rooming house).
