I can vouch for this; I've worked in an office where I eventually correlated my wifi problems to someone in the next room using the microwave.
(Once you recognized the issue, it was easy to confirm the correlation because you would have some connection glitch and yep, it happened just when you heard the hum of the microwave start up nearby...)
