Doesn't seem to cause problems in Cambridge. Both the Hackney Carriage and
Hire Car fleets are mixed and telephone-booked business is mixed between
both fleets because all hire cars use meters set to the same tariff as the
hackneys.

Yes I know

I enquired about booking cab from the office to the station one day and
when I got told it would be 18 quid for a 6 mile journey. I politely
declined

I was expecting pre-booking to offer a discount, not in Cambridge it seems

Indeed, as Colin has said several times recently - they are metered, not
haggled.
