It was after dinner, and I went to brew myself a little digestif. I’d been using the Bruvi for a couple of days, and the water tank was about one-third full: plenty for one serving, I thought. I arranged the cup, put in the pod, pulled the handle and hit the start button. But the machine wouldn’t work. Instead, it began to chime. And continued to do so, sounding increasingly impatient each time. (OK, I may have been imagining that.) Certainly, I was getting pretty impatient.
