Yesterday, I highlighted the auto repair shop in the back alley. Their ability to diversity the service they offer is especially limited. They can increase the range of makes/models perhaps.
With the shrinking of the market for hard-copy newspapers and magazines, newsagents have had to join networks, and diversity the range of services they offer their (usually) walk-in/off-the-peg clients. Take this newsagent, in Darlinghurst Road, just opposite the fire-station.
He carries nearly the full range of main newspapers: Fairfax (Sydney Morning Herald,Sun Herald); News Ltd (The Australian, Daily Telegraph, Sunday Telegraph). He only appears not to carry the Financial Review, which, my guess is his clientele would have little use for. He is an agent for the NSW Lotteries, and for a range of mobile phone service providers: Telstra, Lyca and Lebara. He is an agent for government bus tickets. He is an agent for the airport shuttle bus, has an ATM and a public phone.He has a money transfer agency and a machine for developing digital photographs.
And ... he also flogs ice. How diversified can you get!
