I travelled on a GreenArrow from Lithgy to Edinburgh last month and the main thing I noticed was at Lithgy, several people got on, asked the driver for Princes Street or Edinburgh Bus Station. The driver told them the service didn't serve those places and those people got off and walked to the 38 behind. Hopefully LB/LCB realise there missing out on this custom and extend the route. A novel idea would be to terminate the services from North Berwick, Dunbar etc etc at St. Andrew Square along with the EX services(and other LCB routes) and creating a sort of mini interchange point for services that Terminate within the City but not inside the stupidly small Bus Station.
