A friend who phoned me on Wednesday was filled with wraath "As you know," he said, "I am a booster for Metro. I think the subway is one of the greatest things that's ever happened to Washington. But sometimes Metro's management really makes me angry."

"And this is no doubt one of those times," I observed. "Tell me why you are waxing wroth."

"I'll be glad to," he replied in a grimly determined voice. "When I entered the subway train this morning, there was a questionnaire on every seat. It wanted to know how I got to the subway station, how I would proceed once I left the subway system, and similar questions designed to get facts about the consumer and his needs and habits."

"What's wrong with that?" I asked.

"Nothing," he roared. "What I'm objecting to is that these were business reply cards. After I filled mine out and mailed it in, Metro had to pay the postage on it, Metro had to pay the postage on it. Can you imagine a company that's running in the red wasting all those hundreds of dollars on return postage when all they had to do was put a little cardboard box in each terminal and put a sign on it saying, "Please Deposit Your Questionnaires Here." Isn't there anybody left in Washington who cares about saving money?"

I called Metro and put my friend's wrathful question to an official there. He gave me a soft answer: "We had cardboard boxes in all the stations, each with a sign on it asking people to put their completed questionnaires into the box. Your friend obviously didn't notice the box, and neither did about 10 per cent of our other riders. But 90 per cent did notice, and helped us save money, and I hope you'll tell them that Metro says 'Thank you.'" So consider yourself told.
