I was on the other side of town from where I usually do my shopping once and hit the door of our new, 2nd Wal-mart nearly running as I needed the ladies' room urgently! I rushed past a couple of people and into the stall, and in a few seconds when I was all better I realized that the shoes I could see under the wall of the stall were most definitely men's oxfords. Then I realized the people I had rushed past were not at sinks, but urinals. I did not want to leave the stall! But I calmly opened the door and walked out of the MEN'S room, making no eye contact. Never going to make that mistake again!
