And the story continues... The story of the "never-working" espresso machines!
"My inner accountant quickly convinced me to buy one of those little espresso machines (for the price of approximately 10 tall lattes). It had a steam nozzle to heat milk, which one should clean very thoroughly after each use. I didn’t have the patience to do so. Within a few uses, an unappetizing, dark brown, organic lump developed around the nozzle. A few days later it had become unremovable, and I reverted to getting my coffee outside."
