A
pseudo-
store where you take your
laundry to so you can insert
coins into
washing machines and
clothes dryers and
clean your clothes. Used by those people who don't have
laundry facilities in their place of
residence, usually
apartment dwellers, or the
lower-class types.
Very dirty places, often full of creepy people who seem likely to steal your panties out of the washer when you're not looking.
