In search of a new shower for our home, my wife and I went to a bathroom-supply store.  

We discussed our needs with a young saleswoman. Since it was near closing time, we had to curtail our discussion and made plans to come back the next day to make our final decision.  

Later that evening, my wife and I were at a restaurant, where the same young lady from the bathroom-supply store was now working a shift as a waitress.  

As she passed our table, she suddenly recognized us and  called to me in a loud voice, "HEY! You're the man who needs a shower!"
