It would be a salon/spa-type place, in a mall or
suchlike,
with booths & whatnot. A front-desk attendant to
greet
you, take your money, and direct you to your booth
Walk in, remove your shoes and socks, have a seat...
place your feet in the machine, socks in the hamper,
shoes on the rack.
In
the next five minutes, your feet are washed with
jets
of water, optional scrubbing, dried with air.
Meanwhile,
your socks get a wash & dry, and your shoes are dried.
Optional foot massage.
Replace footwear and carry on your way. Feel like
Jesus did, after he got his feet washed (pretty good
that is)
