I remember a gas station in Capira, Panama that had a sign pointing to toilet. When you followed the path out back, the back wall was concrete blocks partially covered by tile about waist high. LOL.
That reminds me of a time I was in Ireland...drinking with some buddies in a very small family owned pub.
After a time drinking a good number of Guinness, I asked the matron who was pouring pints, "Could you kindly point me to the men's room?"
"The...what?", she asked. "Oh...you mean the toilet."
Raising her arm and pointing her finger to the back of the place she said, "See that door? Go out through that door and you'll be on a small porch. Anywhere between there and Dublin will be what you're lookin' for."
