Why are you calling the borne instead of the main number? I'd only call (or even go to) the borne if I knew there were taxis at the one closest to me. Any additional pickup cost from a further-away taxi answering a radio call is surely worth 45 minutes of my time.

G7 now has an Uber-like app for calling a taxi.
