It's definitely an inner city thing and it's also a Gen Y thing. I work in the CBD with a group of younger people. Our office is above a coffee shop and there are at least half a dozen others within 100 metres. My colleagues are always popping out for coffee, and have spirited discussions about which shop makes the better coffee. Me - I'd much rather boil the kettle in the kitchen and enjoy a nice hot cup of Earl Grey or green tea, but then I am an old fart baby boomer.
