Why are laundromats sexy?

Everybody always presents laundromats in tv shows and movies as this sexy place where you meet horny singles who aren't wearing underwear because it's in the wash.

But in real life, that just isn't true. The laundromat has angry people who don't want to be there, and nobody EVER has sex, or takes their clothes off.

So why are laundromats always presented like that?
