The joke is that you can't just buy the plate > in a quick manner and must order the replacement and will have to just....suck it up. And the absurdity of what such a theft entails.AFAIK the plates are not standard (probably proprietary to that model/brand) so by taking it you probably have to get a whole new microwave if you want it back.

E:thank you for the numerous replies saying they are standardized and replaceable.

It’s vengeance. Pure, unhinged, vengeance.

Honestly, I think a big part of what makes this funny, to me anyway, is the "slighted" phrasing. It's kind of an underused/archaic usage, so it sounds inherently a little funny in this modern context. But it also carries the implication that the original wrongdoing that they're attempting to punish wasn't very serious. Which actually makes sense, as this isn't that annoying, just mildly inconvenient. It will still get hot in there, if you're worried about food cooking unevenly, just turn it 180° halfway through.

I've got one of those. First the plate broke, so we got a new one. Then we moved and somehow lost the rollers. Now neither fit right and I want a new microwave but this one works (except for the turntable sometimes) dammit
