While visiting the Mayan ruins at Chichen Itza I had to visit the ladies room. When I went inside there was a little old lady who, it turned out, had the job of sizing up your needs and doling out what she felt were the appropriate sheets of toilet paper for you. Then, at intervals she would look into each toilet and decide if they were full enough to require flushing. After having read the above-mentioned stories, my story about the bathrooms in some of the remote areas in Mexico is mild in comparison. Even in this USA, I have found that it often comes in handy.
Gas stations are the worse.
Some of the newer all purpose stations have exceptionally clean WCs. USA I went on a two week long raft trip downs the Colorado River, through the Grand Canyon. The river was the only place to pee. If I couldn t find a hidden spot on the shore, I didn t go. OR in the water was completely verboten.
