I recently posted a diary about how I am sometimes able to appear instantly. This happened again last Monday night. I only had six fares (and a cancellation) over the 12 hour shift. Much time was spent waiting between my 'appointments'. One good fare is worth 10 small fares, so at least I didn't lose money.
Usually taxi driving is a solitary occupation, but on this particular night I was sent to offer advice to an overly-ambitious rookie.
