I've had a dual boiler espresso machine (La Spaziale S1) for 10 years that's a typography horror show. There are less than 10 words on the device and they managed to use 4 completely different fonts: their logo font (which I actually like), a squat serif thing for 'S1', an ugly script font, and worst of all for the 'BOILER' and 'ON/OFF' buttons: Comic Sans. It occasionally bothers me but most of the time I'm able to forget about it and enjoy using it.
