This warning comes from the one and the only COO.
Gram got a survey in the mail. It asked her to fill out out and return it by a certain date.
“How can I return this if I have no means of doing so. I can’t afford to waste any stamps on a fixed income, plus I’m too old to be walking 1/2 a mile to the post office for ONE stamp!”
Lesson learned. if you want to increase your mail survey return rate, provide a stamp.
Oh, from the mouths of elders we can learn so much.
