As a regular customer, only broken machines have signs. I have never seen a reserved sign.
Maybe in the daytime when the person working there is doing the wash that people drop off. I always go late night and you can use any washer or dryer that isn't broken, and they. usually have a sign on them.
Wash Up never reserves washers or dryers. Wash Up does not do any wash dry fold (used to - but not any longer). The only thing I can think of is if the machines that need repaired had the sign removed by a client. That does happen - even though it should not.
