Ed Mabry's shop has a toilet. Small, but with the necessary commode and wash basin.

I hope Ed won't be upset with me when I say that it ain't exactly spotlessly clean.

There is a towel rack beside the basin with an old terry-cloth towel that probably won't pass much of a cleanliness inspection. There is a sign over the basin reading:

NOTICE - DO NOT DRY FACE WITH THE END OF THE TOWEL MARKED "A"

No problem here!
