I Am Not Bill, My Name is Lisa

I am not Bill. Bill is my husband and I love him dearly but I am not him. So, why when I take the car in for over $1,000 of repairs and pay with it with my credit card does the repair shop send the "thank you" coupons addressed to Bill? Why, when I order my personal one-year business subscription to Harvard Business Review (special deal just for you!) and send the reply card out from my office, does the "thank you," come addressed to Bill? Why oh why?
