On the way home last night, our family stopped at a local ice cream parlor for dessert. While paying for our order, I noticed a clipboard and pen next to the cash register. On the clipboard was a form that invited customers to join the parlor’s Birthday Club to get a free dessert each year on their birthday. In order to join, all you had to do was fill-in a line on the form with your first and last name, mailing address, email address, and date of birth.
Almost two dozen people had already completed one of the lines on the form, and all of their information was plainly visible to anyone near the cash register.
