The best espresso machine for people who don't know how to use one

When I was at university, I had a very short-lived part time job as a barista. I spent an hour shadowing the outgoing barista and then the title was passed to me. I was a terrible barista, and I’ve often thought I should issue a general apology to anyone who bought a coffee from me. It couldn’t have tasted very nice. I wouldn’t know, because at the time, I didn’t drink coffee.
