Where I'm from they don't exist. But I know what it is, how they work and what they do because I have watched some popular American sitcoms that were made between 1970-2010. If I've learned anything from tired gag setups it's that they're a magnet for wedding rings and jewelry.Where I'm from, garbage disposals are pretty rare and when I got an apartment with one, all my friends were like, "But where does the food go!?" and staring at it like it was an alien device.
So people can be like this.
