Ethical dilemma:

You are in a public laundry room or a laundromat that has no attendant. You
have two loads of laundry. There are two washers free. One washer is in
perfectly acceptable condition, and you put one of your loads in this
washer. The tub of the other free washer is full of bits of yarn and other
unidentifiable matter, and the surface of the machine is covered in pieces
of hair of unknown origin. There is another machine that has just finished
its cycle, and there is no one around to collect the clothing from this
machine.

What do you do? Do you take the clothing out of the third machine right
away? Do you wait for an acceptable grace period and then take the clothing
out even though there is technically a washer free? Do you attempt to clean
the empty washer?
